My new favourite underwear: Hamilton & Hare lyocell

||- Begin Content -||

*My experience of this underwear in the months since has not been as good, and I would therefore not recommend it as highly. I experienced quality issues with both the waistband and the material*

Long-time readers may remember The Underwear Project in 2011, which involved trying every major producer of luxury men’s underwear to see which I preferred.

Zimmerli won that competition, and I’ve worn pretty much just Zimmerli underwear ever since. (The loyalty was reinforced by visiting the Zimmerli factory in Switzlerand for book The Finest Menswear in the World.)

Recently, however, I needed to replenish my supply and balked slightly at Zimmerli's prices, which are now mostly over €70 a pair.

I therefore tried out three other brands – Sunspel, TM Lewin and Hamilton & Hare – looking for an alternative.

Now, some of my criteria will be common to lots of people, others will be very personal. Breaking them down, they are:

  • Longevity. Probably the most important aspect of quality for most guys. They should wash and wear well without pilling, losing shape, discolouring or coming unstitched.
  • Luxury. Must have a luxurious feel, which could come from a fine pure cotton, another natural material, or a mix with only a small amount of stretch synthetic.
  • Fit. I wear boxer briefs/trunks, and they must fit well enough to be entirely forgotten about the whole day, never riding up the leg or requiring any other surreptitious adjustment. An issue for someone with a fairly small waist and big bum.
  • Simple. Minimal branding, one colour, certainly no loud multi-coloured waistband.
  • Mid-grey melange. More flattering than black, lasting better than white, and as I learned in the first Project, unfortunately about 20% more expensive as raw material.

I included TM Lewin in the list – which I’m sure will surprise some readers – because a friend swears by them. Said they’re cheap and feel as good as any designer brand.

TM Lewin does do a grey-marl boxer brief for £14 (above), with only subtle branding on the waistband. It did fit well, and feel nice.

But it didn’t last. Compared to the others, the material started to pill and otherwise deteriorate after about 10 washes.

Next, Sunspel. They do two stretch-cotton grey-melange trunks, in a long and short leg, for £28 (above).

They were good. Solid. Felt really nice, the long leg fit particularly well, and there’s no branding.

They held up very well too, as well as the eventual winner, from Hamilton & Hare. I’d recommend them both.

The reason I ended up going with Hamiton & Hare (above) was mostly the material.

A new range they launched last year is made from Lyocell – the cellulose material made from Eucalyptus tree pulp. It’s similar to other natural alternatives like bamboo and modal, but has zero waste processes, requires no chemicals or pesticides, and uses 20 times less water than cotton.

I confess these environmental benefits were of only secondary importance though.

Mostly I was taken with the feel, which is similar to fine cotton but softer and silkier - fine yet robust.

There is a pair in grey melange (above) for £35 in a mix of 64% Tencel (lyocell brand), 32% cotton and 4% elastane. These performed really well. They breathed well, fit well, and have lasted well.

Hamilton & Hare are keen on a few other design points too, such as having the waistband covered in the fabric, rather than just being elastane. I haven’t noticed a difference in comfort here, but others might.

The label is also on the outside at the back, again to increase comfort. Personally I’d prefer something printed on the inside, so the outside is free of all branding, but it’s a small point.

I also tried H&H’s tubular underwear, which should be comfortable in the same way as T-shirts made in the same manner, removing the seams. But I found they were too flimsy for me, and rode up.

So a five-pack of the grey melange lyocell it was. At £155 for the pack, it’s still £31 a pair, which isn’t cheap. But it’s a lot less than Zimmerli.

Interesting post, Simon – I have just gone over to H&H after trying out some other makes. Previously made mistakes in buying underwear – poor fit, badly out of shape after a few washes etc but the H&H are excellent. Very comfortable fit. In terms of value they are slightly pricey but not when compared to the horrendous designer brands with the dreadful waistbands.


Hanro number one for me


I think the price is £155 not £115. As per your link


Interesting post Simon, however how would you compare it against zimmerli?


I purchase my shorts at Emma Willis, which at 60 GBP per, is not cheap. However, the cloth-lined waistband adds to their comfort and they last. Linen shorts are my favorite, although they do loose some shape w wrinkles.


I concur. H &H have been my go to for years now. Little complaints from me there.

Frederick Threepwood

Bearing in mind that they will inevitably end up with skidmarks and yellow stains in them one might as well go for cheap and cheerful M&S @ £25 for five pairs.



Hahaha. A little bit more information than we need. This being , toilet paper works wonders when used properly.

Lota user

Gross. You should always wash with water after going, like a billion+ people around the world already do. No skid marks or stains in my undies, ever. Hopefully Simon can recommend a luxury lota to discerning gentlemen…


Carrying a lota around is not very practical. 😉


Wash at max 3 degrees cel.!? That is certainly not what the experts in hygiene recommend for underwear, but rather 60 degrees.


Their recommendation to wash at 30 is what puts me off trying them.


I agree


Good article. I have also been buying Zimmerli for years (based on your recommendation) but find them too expensive and maybe not that flattering. I am now trying a Swedish brand, CDLP, that is also using lyocell. I dont know if you have tried them. They seems very good but I havent washed them that many times yet.


CDLP has been very successful in making a big buzz in the media. I’ve never tried them but they’re on my list. If someone has, please share the experience.

Christoffer Öhrström

I have a few pairs that I’ve used for around a year now. I own 1 pair with regular legs and 3 with shorter legs. Both works very well and I barely notice I am wearing them during the day. Compared to my underwear made in cotton CDLP feels much fresher at the end of the day.

I am washing them in 60c and haven’t noticed any degradation, for now.


I can also confirm the above, CDLP’s lyocell boxer trunks are my favorite after having tried many other brands, the feel is phenomenal (and also more luxurious than any cotton variety I’ve tried) and I’ve had mine for about a year now. Apart from the inside label washing off I did not notice and deterioration in stitching, fit, or feel. Price is great as well.

The only downside for you, Simon, might be the non-melange gray (I find their deep burgundy and green gorgeous colors though) and the ever so slight branding on the waistband

Also, I second the recommendation for Emma Willis boxers, my other go-to choice for some time now



What temperature do you launder you knickers at? I use minimum 60c (which is what is recommended for underwear as anything colder doesn’t kill the bacteria, ideally one should was at 75c I suppose). I assume this would affect the durability of these pants quite a bit?

Have you tried H&M’s btw? Cheap and cheerful and last surprisingly long even at 60c cycles.



Perhaps it could be an idea to do a piece on how to weigh different arguments for washing temperatures – hygiene vs longevity vs sustainability? We’re urged more and more to wash at lower temperatures, and allegedly detergents have gotten more effective, but it would be interesting to have a scientifically informed, sartorially inclined overview of the different pros and cons.


On this subject, a post rounding up the best clothing care products would also be useful (alongside your many helpful videos on best practice). Perhaps as a follow up to “Clothing Resources: Places to Clean, alter and repair”, featuring the best detergent, fabric softener, stain solutions, suit brushes, sweater brushes, irons, steamers, moth deterrents and so forth… Probably not individually things that could justify a post in their own right, but still as a whole it would be useful to have a directory of your recommendations. It’d be good to know, for example, whether you recommend splashing out on The Laundress detergents or sticking to Persil…


For a few years now I have stopped using the dryer to dry my underwear to try and make them last longer. What are your opinions on using the dryer? I am thinking of going back as I constantly have underwear on the drying rail.


I’m not sure that Simon wears knickers. Well, each to his own.


Interesting. Will have to check out.

I’ve been a Derek Rose fan for both PJ’s and trunk style underwear like those reviewed for a while. Love them and similar prices. Worth checking out.


Sunspel underwear and tee shirts are superb. They fit well, hold their shape, and are very durable with no branding on the underwear, highly recommended. In fact, Sunspel is just a fantastic company in general, making excellent,functional products.


Similar to Carl, I have also started using CDLP satisfactorily thus far. I have also been curious to try The White Briefs organic cotton.


Have been buying my briefs from Calida for a few years now – their Focus line is real good – it’s tactel based too, a pair of briefs retails for 30 Swiss francs


The choice in this area of menswear is, fortunately, very wide. As with many readers many brands have been tried but the one that, for me, offers the best fit, lasts through many washes and remains reasonably priced is Sloggi. A brand of the Swiss based Co. Triumph (est. 1886) the quality of cotton is high and remains comfortable for a long time. My pick from the range is the midi (£23 for 2 x pack).

What is the rise like on those pairs of underwear?

I often struggle with the back rise on aftermarket underwear as I also have a full seat. I found a Tommy Hilfiger Modal/Cotton a couple of years ago in a good mid-rise cut with a high back rise but it is no longer on offer.

Jordan Healey

Patagonia recently released some lyocell underwear that are a perfect replacement for the ones I mentioned, and the rise is quite generous at the front and back.


Simon, have you ever tried anything from Cagi, Perofil, Schiesser or Bresciani? All make wonderful underwear — including t-shirts, singlets and long thermals — for comparable prices. Might be worth you trying out.


Bresciani makes my favorite socks so, the underwear is certainly worth a look.


Would commend looking at merino underwear as well. Soft, wears well, resists odor. Mostly marketed in athletic clothes here in the states, but are now my favorites. A company called ridge merino makes a pair that is a merino-Tencel blend. Quite affordable too, relatively speaking.


I have been using bjorn borg for a while now and they wash and last well and very comfortable aside from the label, which i unpick when i get them


No photos of you wearing them? Your fans demand it


I see potential for a Permanent Style spinoff: Prominent Seat.


Premium membership revenue stream


SAXX. Their slogan „life changing underwear“ is maybe a slight exaggeration, but their unique design makes them so much more comfortable than anything else I ever tried.


I see no mention of Derek Rose underwear?
I personally use Sunspel briefs as they are 100% cotton and extremely comfortable. They last long and, at £25 per pair good value although even at this cost, i feel it is expensive.


For cotton boxer shorts, the value of Uniqlo boxers cannot be beat. Long-lasting, 100% cotton, with back seam, in oxfords and striped broadcloth. Get them for under $5/pair on sale.

On a separate note, does anyone know where to find quality silk long underwear? It used to be possible to purchase silk long johns of adequate thickness; now from the few places that offer them they are so sheer and get runs like pantyhose in no time.

I will try H&H based on this, but I’d still put in an argument for Zimmerli despite the price. First they are virtually indestructible and barely deteriorate. I’ve only had one pair last for less than five years, which is astonishing for underwear. They resist odour brilliantly — the same pair of Zimmerli briefs works for a twenty-five kilometre Alpine hike and a board meeting two days later, with just a quick soak and handwash in a hotel sink. No other brand I’ve ever tried has that versatility. Yes, the price is eye-wateringly high. But they are sometimes discounted in the annual sales and if one stocks up then at ca. 55 euro/pair, the quality still seems worth it.


Saxx isn’t bad but Bn3th (formerly MyPakage) has a more comfortable pouch technology…however I like Naked especially the micromodal or tencel

Patrick Humphreys

I swear by filoscozia underwear from Italy. A vast source of quality garments, seemingly untapped by the menswear community. Recently sampled pieces from most of the popular producers of this stuff. Garda provide the best value for money, is my conclusion. Briefs can be had for around £5 and undershirts around £11. Compared to conventional ‘luxury’ underwear, I have tried Sunspel before, for instance, and filoscozia is leaps and bounds ahead at a fraction of the cost.


Zegna do some nice underwear. I paid £36.00 for a pair in (I think) 100% cotton made in Italy. I’m also eager to try La Perla men’s underwear.

Of course there is old school (from my teen days) Calvin Klein underwear although I don’t normally buy them anymore unless they are on offer at CostCo.

I recently bought Falke boxers and Prada briefs. Prada are a little weird in the fit, I’m yet to wear the Falke boxers.


Have you heard of BN3TH? The most comfortable underwear I have found. They used to have a line made with Icefil, which I think are the best, if you can still find them through resellers. Otherwise their top of the line is The Pro 2.0. Definitely worth a try.


Being a cyclist, my experience with man-made fibers derived from cellulose, like Lycocell, Tencel or Modal was quite disappointing. Boxer briefs with 5% Elastane and 95% Lycocell tended to fray after approx. 15 wears, whereas blends with 55% of Lycocell/Modal and some Cotton lasted better but were still inferior regarding the longevity to cotton with 5% Elastane.

It is nice to see that many brands are moving to a minimal branding. So far I have had good experience with Calida and Mey,


Simon, interesting topic.

I have noticed that “manufactured” or even synthetic fabrics have come forward leagues in their development for comfort, breath-ability, and odor retention.

Years ago, it would be 100% cotton only that could provide a comfortable wearing. These days, except in rare cases, I find cotton is lagging in performance.

The new micro fibres have one by one tackled the issues listed earlier, and have conquered them….

I am finding that many dress shirt manufacturers are using some of these new synthetics…..Simon, do you have any opinion on these? Is this a growing segment? I believe a couple years ago, you touched upon the new blends for use in suits….


I will certainly try some H&H boxer briefs, having read this informative piece. For the last few years I’ve been wearing Derek Rose. They are very comfortable – they pass the “don’t know you’re wearing them” test. Discreet branding. Hold up very well after hundreds of washes. Good range of colours/patterns, from plain vanilla to quite ornamental.


I have tried Derek Rose, Sunspel, Hanro and others. They are all nice, with great fabrics. However, none of them fit me well. I exercise a lot and have a prominent rear, which is not accounted for in these cuts and leaves too little room up front as well as in the back. Does anyone have a recommendation for a brand that is high quality but is also a lifter’s cut?


You should have a look at Seagale and their action Merino/lyocell boxer briefs. They have plenty of colors, minimal branding, printed label and the feel is wonderful.


Some of these comments really didn’t leave much to the imagination


I cannot recommend H & H. Their sizing is all over the place (their mediums in one style are large in another). Over the years I’ve tried a myriad of undies in the quest for comfortable support: H & H, Calvin Kleins, M & S, Superdry, Aubade, to name just a few. I hated some of their thick elastic waistbands. With many, I could not get comfortable support, leading to me being from time to time told off by my wife for “fumbling” (even more embarrassing if you’re in a public place – how do you “fumble” discreetly in order to get your bits in the right position?) So in answer to the guy asking about silk and to tell you all where I found my solution do head over to online retailer “Patra”. They are primarily a ladieswear supplier but do a small range of underwear and pyjamas for men. Their silk “packs of three” cost way less than what you’ve been discussing here (they also do a silk/bamboo mix), you can machine wash them and best of all, you get your tackle supported while feeling (with the silk) as if you’re almost going “commando”. The recommendation came from my elderly Mum, and mothers do know a thing or two about addressing the sagging effects of age…..


By the way, Patra’s silk socks are also great: perfect for hot weather.


Personally, i cant effort that much on the bottom underwwear (brief),

And i picked Jockey as my favor brand for the brief, it is soft and comfortable with cheaper price, but i understand it is very personal

BTW, beside the underwear, is there any topic regards on undershirt ? if it do, i really recommend the brand “ribbedtee”, made in USA , especially the deep V tan color undershirt, prefect to wear under the shirt (

Please do let me know if any other alternative


For what it’s worth I thought I might share my experience of the Hamilton & Hare Lyocell underwear referenced in this post. I was recently on the hunt for a new brand as the JCrew underwear I really liked changed recently (for some reason they’ve messed with their sizing) and so I checked here for any recommendations and after reading this article purchased a pair of the Hamilton & Hare. Quite shocked to say that my experience of them seems almost the polar opposite to Simon’s. The material itself is undeniably lovely but that’s where the pros end for me. I’ve never had a pair of underwear ride up so badly. I also found their Medium to run on the small side (I’ve a 30″ waist and found their Medium uncomfortable with them leaving an actual mark around my waist). Worst of all was after the first day of wearing them (and this was after having washed once at 30C and no tumble drying), as I took them off an enormous amount if fabric fluff fell to the floor. Examining the interior of the underwear I found that it had badly pilled after just a single wear. I’ve never encountered anything like this and so will have to continue my hunt.


In the interest of fairness I’d like to add that Mark from Hamilton & Hare has worked hard to resolve the issue for me. It’s clear they take such things very seriously. Hopefully my experience was an anomaly


I tried these. They are comfortable and a good fit. I find the label on the outside a little irritating and occasionally means I put them on inside out (not my sharpest first thing in the morning!). I also find the closure system not up to much; frankly it doesn’t keep everything tucked in which I can imagine leading to a variety of embarrassing situations! For me the search continues…


Personally, i have swearing issue on my bottom, especially the front part.

i have such experience with other brand. Boxer, it will be fine for me, but it will be too loose, and my tailor trouser doesn’t fit well when i sit down. Breif, it will be too hot for me.

Do you think H&H do better ? and which style i should pick in that case?


Hello Simon, I’m curious to know where you shop for underwear now? Or more specifically, which brands you’d recommend after all these trials?


Hi Simon, could you elaborate on the disclaimer now added to this post? You say you’ve had some issues?
Re. Sunspel, a few years ago i gradually upgraded all my boxers to Sunspel but found that they didn’t last as long as some of the cheaper pairs i had [uniqlo being the best]. They discoloured very quickly and frayed at the leg openings. I gave up on them after about 18 months and went back to uniqlo.


Good sturdy pants for me please. The Uniqlo one are 100% cotton and will last twice as long. I would argue from a sustainability point of view this has to be considered.


I would like to share my experience with the Hamiton & Hare briefs that I bought about 1 1/2 years ago. Until a few weeks ago, they really held a good shape. However, after that the condition of the fabric deteriorated very quickly for reasons I can’t fully understand. At the top of the waistband, the fabric has worn away very quickly and now the elastic is visible throughout. Also, at the bottom of the waistband, right at the seam, the fabric has torn at the points where I pull on the underwear when putting it on. I’m really puzzled by this rapid deterioration, especially since I’ve always treated the briefs with care and had a great many in circulation. Although I love the fit, look and feel of the briefs, the lack of longevity is an absolute no-go for me. I will not be purchasing these briefs again.


When Tom Ford brought out underwear I bought a pair. Needed some new underwear and truth be told it’s about all I could afford from Tom Ford. They are really comfortable and I also like that they are Made In Italy.

I was about to order another pair today and noticed they are now made in Bosnia & Herzegovina.

I often attach good quality and higher prices to the “Made In Italy” label.

Should I be disappointed? Love to get readers (and Simon’s) thoughts.


I’ve ordered them so will see how they compare.


i found some people recommended CDLP, and then i give it a tried, the result didnt went well for me. As i have a sweating problem, the 100% lyocell material didnt absorb the moisture, and i also found cotton is better in my case
@Simon, do you have similar feeling with H&H (all the year), or some proportion of cotton may help?


@Simon, you are right, i just received some Sunspel underwear from online store, they are great, and the long leg one fit particular well for me, i love that very much. Thank you for your advice


Simon, have you experienced commissioning bespoke underwear from a shirtmaker? Would you recommend it?


Simon, do you still swear by those Sunspel boxer briefs? At £40, they seem like an excessive amount of money to spend on underwear. I happen to have found some lyocell ones at Muji that feel quite nice, though I can’t say yet how durable they are.


I agree with another poster here for Hanro. Great quality, great fitting though sometimes comes a bit tighter than others and decent price.

Ash Qureshi

Ok — so a very first world problem. Am a huge fan of H and H (particularly after Sunspel seemed to change its cut). But the seem to have closed down. Got about seven of the Kyocera cotton boxer briefs in a panic but does anyone know of another make that comes close in comfort….

Lindsay McKee

It appears from the website that Hamilton & Hare are sadly gone?
What happened?


Hi Simon could you possibly recommend somewhere with the same comfort level.
Where are you going to be shopping now they are gone?

Per S

I bought my first pair of underwear from Asket in 2017, and have gradually replaced other brands since. Have been rotating a dozen or so, always washing on 60 degrees. All waistbands have been holding up. Discovered a damaged seam and thus discarded my first pair in late 2023.
