Rated 5 out of 5 by from Bravo, Icebreaker All the years I have been wearing Icebreaker products, I have never found a boxer brief that perfectly fit my needs...until now! Excellent for active wear such as hiking, biking, and running. Wicks well, fits well, stays put (no riding up). Congrats Icebreaker! Well done! Now, if you ever make these in a 9-inch inseam, I will be getting at least 10 pairs!

Rated 3 out of 5 by from Merino makes the best underwear I bought a few pair especially for travel. It's so nice having underwear that can stand up to a few days of wear if need be and not get too funky. Plus they dry fast if they need a wash on the go. Unfortunately this particular pair isn't made with a fly. Maybe I'm the outlier but I find not having a fly in boxer shorts really annoying. Icebreaker, please don't go the way of Mons and not offer a fly on anything. Each style should have both options.

Rated 5 out of 5 by from Best of the Best I purchased Icebreaker's Anatomica Zone boxers because I already have just about every other wool boxer brief in the outdoor market, and I'm bummed I didn't discover Icebreaker sooner. I own 6 pieces from them now, and every single item tops anything I have from competitors. These briefs offer more range of motion and temperature regulation than any other brief I've ever worn. These will be my go-to performance briefs. Thank you for your work and transparency, Icebreaker! You guys have set the standard for the rest of the industry and truly are the best!

Rated 5 out of 5 by from Solid. I started experimenting in the world of merino about 6 months ago and have been buying boxer briefs across the board. (I am an Exofficio Grab-N-Go convert) Hence, I'm six months into my pair of Anatomica Zone Long Boxers and they are becoming my 'go to' when I go out for physical activity. The fit seemed a little snug over the first couple weeks but I seemed to have hit a 'sweet spot' that has me grabbing these before other boxer briefs when I go out for a run. The material is thinning a bit but no rips or tiny holes to report as of yet. Good comfort and the odor control of merino really is a difference maker. Time will tell if the price difference is justified. I bought these on sale at a price of $36. Thus far I can say I'm happy with the purchase.

Rated 5 out of 5 by from Best Running Underwear I've Owned I've been running for about 8 years now and tried various different underwear but haven't been happy with any until I found these. I purchased 2 pairs of these and wore them everyday alternating between the two. I run every and have run 1 - 26.2 miles in these averaging about 4 miles per day. So as you can see I have put them to the test and after a year of running I wore a hole through them. My cadence is about 190 so that is a lot of rubbing. They are a bit on the pricey side but I love them and will continue to use them.

Rated 4 out of 5 by from Very comfortable These are very comfortable. Nice length and snugness. I did not notice when ordering that it does not have a functioning fly. the waist band is a little wider than I prefer but I’m keeping them because of comfort.

Rated 5 out of 5 by from comfy and temp regulating Der Stoff ist wie von Icebreaker gewohnt sehr gut, der Schnitt erinnert mich an die Bilder der kurzen Hosen der 50 er, aus meiner Sicht wenig kleidsam.
