    • Runs small, but 83% wool
Color: Black Size: Small
Runs small; Menโ€™s size Small was MUCH smaller than any other brand of underwear I own. As other reviews have mentioned, the pouch is a little on the snug side. But I can live with both of these things for the 83% wool content. Great for lightweight travel when most other brands only offer long-legged boxer briefs that add weight when I donโ€™t need it in my bag. ... show more

    • Runs small
Color: Jet Heather Size: Medium
You should order a size up as the sizing isn't correct. If you would normally wear a medium in other brands order a large for this brand.

    • Bafflingly small
Color: Black Size: Medium
I've always worn size small briefs. From every brand, small always fits me. Except this pair of underwear! Size small was comically tiny, so I exchanged for medium and they were still ridiculously small. I'm not sure what universe this sizing comes from, but if you wanna give these a try, recommend going up two sizes. ... show more

    • If you are looking for 100% wool that will last, these are great!
Color: Poseidon/Hydro Size: Small
Icebreaker brand is awesome. 100% wool and the fit is great. I'm 28/29 waist and Small was perfect. Sides could be smaller since I wear these under long johns most of the time. Front fits perfect and keeps me in the position that I want to be. I am not a fly guy. Haven't used one since I was 12 because I find them in general way too small to snake anything through. But if having a fly is your preference, take note - you may not like these. Color is good, it's something different. Material is the right thickness too because they don't bunch or ride up. I have several pairs since I am on the ice a few days a week. I tend to wear a lot of wool in the winter so I end up doing a load of wool garments on the 'Hand Wash' cycle separately. I use biodetergent and hang dry. I've had some pairs for 8+ yrs and they are holding up well with no holes, stretching or shrinking. I am guessing it is because of the washing method I use. Had they gone through the regular wash and dry, they may not last as long. I'm sold on them and the Icebreaker brand so two thumbs up! ... show more

    • Used to have a ball sack
Color: Jet Heather Size: Medium
Icebreaker used to make these with a nice pouch for your junk and they no longer do. Your man-stuff will feel a bit of pressure as the fabric's natural tension holds everything together vs. a junk-specific pouch that they used to have that housed your man goodness. So now, the boys are a bit more squished than they used to be because of cost cutting. A drag. Other companies make merino undies with pouches for the boys but their fabric isn't as thin so it's hard to wear with fashionable pants... I am a reluctant purchaser since the design change which happened sometime back in 2016 I think. HEY ICEBREAKER!! BRING BACK THE POUCH!! Especially on the boxer briefs!! ... show more

    • They'll work. Barely.
Color: Midnight Navy/Granite Blue Size: Small
I like the fit up front, but they could be a little more snug in the back around the thigh opening. Edit: After further wearings, I've changed my opinion of the fit in front. Perhaps a larger size would've been better, but the thigh openings would then fit even worse than they do now. I wish I could like them. I bought another brand at the same time, and they fit as bad, but are TOO big in front - they feel like granny panties. โ˜น๏ธ ... show more

    • Just. Copy. The Cut of the Hanes Brief. Already.
Color: Black Size: Small
It is nearly infuriating to try wool underwear. It is as if "wool" means - crappy cut, lack of elastic where there should be some (i.e. around the leg) and did I mention, the crappy cut? All the wool underwear (except for the briefs from Smartwool, thus far) is either waaaay too small (as this Icebreaker version is) for a size Small, or waaaaay too loose and unsupported (as is the case with Minus33). Why can't you just trace the general cut of the classic Hanes Briefs in the respective size? And, don't forget to put the elastic around the waste AND around the legs. ... show more

    • Bring the originals back!
Color: Midnight Navy/Cadet Size: Medium
I've had several generations of these, and these could be the last. The fit changed (medium now = small a few years ago), as did the styling and fabric. The early versions (with a diagonal seam across the front) were nearly perfect though the material was more fragile. These have become slightly more high waisted and have a slightly more conservative cut. Fabric is more durable, but over the course of a day can get a little baggy in the seat and legs. Hoping that Icebreaker comes to their senses and returns styling and fit toward the older style. Overall I like the (mostly) wool performance. I was happy that I had an easy go-to choice for several years, but may now need to reconsider. ... show more
