Product Reviews
Rated 3 out of 5 by from Great Materials, Subpar design [This review was collected as part of a promotion.] I really wanted to love these shorts! I've always dreamt of wool running shorts and these seemed perfect. And the lining and shell and pocket designs are all amazing. However, I've consistently noticed the lining bags and bunches around my groin during my run. I can minimize this by tying the waistband really tight, but then that's not too comfortable, and usually takes a mile or two fiddling before I can get it to run smooth. Dear Icebreaker, check out the Patagonia Strider Pros for a similar design with a great fit. I hope you can refine this design because it's so close to my perfect shorts but unfortunately not comfortable to run in.

Rated 5 out of 5 by from big legs and showing some thigh These short are very well made and comfortable even if you have larger thighs for a few reasons: 1) wide leg hole opening, 2) short so fabric doesn’t cling to big thigh, 3) built in merino brief rather than compression short. I sincerely hope that they don’t convert these to having a compression short built in like so many other companies have done with their shorts. It’s just not as comfortable for those of us with large thighs. Also the merino brief resists odor better that polyester or nylon over time.

Rated 4 out of 5 by from Great, but... Faulty Seam Adhesive Terrific in every respect save one: On receipt, I noticed a tiny separation in the crotch seam. On wearing the opening soon began to lengthen. Within 2 weeks it was an inch long. Stopped wearing it to prevent further opening. I'm going to buyi seam repair tape, the stick on type, not the more industrial hot pressure adhesive. Should work.

Rated 4 out of 5 by from great materials, but design could be better The nylon outer to the cool-lite liner, everything functions well as intended. I am 6' tall and 155 lbs (30.5-31.5" waist) with developed legs (run a lot); I usually fit small in running shorts, and wear small in IB's Anatomica Boxer's w/Fly (medium in boxer's w/o fly). These shorts in small fit perfectly, not too loose, not restrictive anywhere. The legs are loose enough to allow nice breeze, but don't flap around or ride up. Very comfortable in use, no chafing, no soaking in sweat. But I'd like to see a simpler, more traditional runner short designed out of the same materials. The wide mesh pockets seem a bit overkill, since someone going out on a long trail run is likely to bring a pack or handheld. And another reviewer mentioned the zip pocket being wider than the zipper, which can get keys stuck in the edges—I experienced the same. I don't mind the nylon, but would be awesome to see a more traditional runner's short cut and materials entirely made out of cool-lite, like a lighter Momentum short.

Rated 5 out of 5 by from Great trail shorts I have had multiple pairs of these and they are great for trail running and traveling (remember those days?!). I can take one pair on a week long trip and run everyday without worrying about the odor riding in the elevator back to my room on day 7!

Rated 1 out of 5 by from Inner lining is way too tight I agree with other reviews. The inner lining is tight and uncomfortable, rendering this a non-starter for any sort of wear. Given that I purchased it on final sale, I cannot return it either. Very disappointed. I also purchased this with the intention of reducing the amount of plastic-based athletic wear I own, but literally only the liner is made of merino (and a blend at that), and the outer shell is plastic-based.

Rated 5 out of 5 by from Holds true to the description These are great shorts for exercise or just being outdoors. The feel great, don't get smelly, dry quickly, and are easy to wash when you're on the road. I liked my first set so much I bought a second one.
