I intended a brief stint in the Anatomica Bowers. Things changed and a rescue in the wilderness was needed.27 hours later We found him and we were headed home. It was hot out and I was very active, sweating my way through a demanding day. Results? No heat rash, no chafing, no soggy spots, no regrets.It's hard to refer to the anatomicas as a product, they are so much more. Protection, comfort and a secure solution to a nasty set of problems.

Great for the first few months, but these start thinning along the saddle seam that joins the front half to the back half. I've also had to mend a few along the side seam where the surged seam didn't catch both pieces of fabric. Not as "premium" as you'd expect. For comparison, underwear from a smarter wool brand is older and has not shown any similar signs of wear. Only expect to get a year out of these.

I've given up using bike shorts, in favour of these durable, non-irritating, comfortable merino undies.I wore them almost continually on a 4000km cycle tour last European summer over 3-4 months in 38C stinking hot weather, and never had the customary jock itch, seam "lump" or even infected sweat pores or hair follicles. Hastily rinsing them in fresh water was all we managed about every 2nd day due to filthy natural water sources and isolation. I bought another pair on our return as I was so impressed, and there's still no holes or stitch failure

I have a 31-32 waist, 29" inseam, lean, athletic build, especially legs. I wear a M in everything but often a L in shorts for the leg width (mainly cycling shorts). I have tried all the IB boxer fits and then the past 12 months found the "long" and won't go back. The regular anatomica boxers were so uncomfortable riding up but I wore them for years rotating at least 20 pair before finally giving up. The general wear was great - some would tear at the leg after a year or two of tugging them down, but otherwise held up well. The long length is perfect even for someone with a shorter 29" inseam. After a number of washes the legs of the Large were stretching out and also beginning to ride slightly (never very far), but only have several hours driving or walking, ... MoreI have a 31-32 waist, 29" inseam, lean, athletic build, especially legs.

After a number of washes the legs of the Large were stretching out and also beginning to ride slightly (never very far), but only have several hours driving or walking, sitting/standing. The L are still "anatomic" yet a comfortable, snug fit. I've just this past week ordered 3 pairs of the mediums. Legs are just a tiny bit tight at the seam out of the dryer, but I can tell I'm a medium in these shorts which might mean they fit a little big given the size of cycling legs. Expecting the long to be even better in hot humid conditions and long travel days. Only complaints, more colors please (and nothing so odd like IB products colors have been over the years). Also, why the white lettering on the band on the grey boxer when the black has darker? The white looks tacky if it shows out of your shorts/pants. IB is not CK.
The wool fabric is fuzzy, thin, short fiber, low quality cheap-o stuff. Nowhere near what it used to be. Total rip off. Even at 30 percent off sale. This is my third generation of icebreaker stuff over the years, and every time it get worse and worse as they cut corners.And because the fabric is so cheap, it does not hold its shape so it sags and bunches, and looks quite flimsy and fragile.I think I'm done with icebreaker.
Are these coming back? There is nothing else like the Merino Anatomica Seamless boxers on the market. I bought one pair in 2020, and then two more in 2021 (not the long version, but I can't find the regular length on the website right now). I should have bought more. I reserve the three I have for travel and motorcycle riding, and they are all still excellent. I like that the waistband is the same material as the short, and as a woman, I appreciate the lack of excess fabric and contoured pouch in the crotch. This fabric and cut perform better than anything else I've found. Please bring these back.
You get what you pay for and this is very true with these boxers. I love the long size in the leg, and for me, it is totally worth the extra to get the long fitting. With this fitting, they don't roll up the leg when doing active activities or from day to day life, perfect to have this option. This adds to the comfort for wearing these boxers.The sizing is slightly different to the normal UK so I found myself in between a medium or large size, normally in the UK sizing I would be a medium but for Icebreaker I have found that Large is a more comfortable size although a little loose because it's the size up the medium is just a little too tight. It is just a shame I sit right in the middle of the two size brackets on Icebreaker.I've not had any issues with these ... MoreYou get what you pay for and this is very true with these boxers.

Thanks, Icebreaker for producing such a beautiful item of clothing which I have confidence in and as so comfortable.
They're amazing, genuinely feels like you're wearing nothing at all. Super breathable, no chafing, never sweaty and they fit like a dream. They're not cheap but they're definitely worth the price.I first bought these a couple years ago but just bought a fresh few pairs for my gap year. Currently wearing these in my trip to the Sahara Desert and honestly they are heaven. I genuinely couldn't imagine going back to any other underwear after trying these.
I initially bought 3 pairs, on e for a mate and 2 pairs fo me as we both wanted merino and a longer leg.was a bit underwhelmed with the elastic waist band not being too strong, narrow and not a firm hold. Then I thought nah I'm just being picky but after a few months the waist band isn't great and rolls over r as another review has mentioned also. Should put Icebreaker on the back of the waistband and do some free advertising. The size chart said medium but they were a bit tight but probably had I gone L the legs may have been looser and I have pretty solid quads. Pouch could be a bit t more formed and longer meat and boys, wouldn't run in them or you'd have slippage. Merino scratchy.All in all a bit overpriced but couldn't be bothered sending them back. My $24.00 ... MoreI initially bought 3 pairs, on e for a mate and 2 pairs fo me as we both wanted merino and a longer leg.was a bit underwhelmed with the elastic waist band not being too strong, narrow and not a firm hold.

My $24.00 Aldi ones win for me. Sorry Icebreaker was hoping for more at this end of the price range.Packaging must be worth $10.00 get rid of it it's merino, natural go for some eco.package...men don t need a sexy box that goes straight to the bin.
so disappointed with these. i expected more from icebreaker than lame greenwashing claims. instead, i got a pair of underwear that after a month the plasticy-elasticy coating that makes these stretchy started delaminating (always cold-water washed, hung to dry) and now, after a little over 6 months, has completely delaminated and shed its microplastic self into laundry wastewater. i'm not sure how "corespun" fabric delaminates into the droopy baggy mess these have become.
