[ I got these Tommy John 350 Sport Micro Boxer Briefs for my husband, and they ’ ve been a hit. He says the 6- inch inseam stays perfectly in place, even during workouts, with no riding up. The micro fabric is lightweight, breathable, and keeps him comfortable all day long. He appreciates how snug and supportive they are without feeling too tight. The waistband is soft and doesn ’ t dig in, which he finds really comfortable. Plus, they ’ ve held up great after several washes — no fading or stretching. The 3- pack is a fantastic value for such high- quality briefs. If you ’ re shopping for someone active or just looking for durable, comfortable underwear, these are a great choice!

[ I discovered merino wool a couple years ago. It is the perfect material for underwear. It is lightweight, dries easily and no odor. You know how an active girl sweats in the summer- when everything, including your underwear is wet from sweat? This is no longer a problem with hipkinis. No matter how sweaty you get, your lady parts are dry! The fit of these hipkinis is great, too. Covers your entire bum.

Jakie
[ I have recently started wearing merino undies, and these are the best! They fit well, wear well, and wash/dry quickly. They are great for travel! They are particularly nice if you live in colder climates where you must wear multiple layers to stay warm, including long underwear, but I 've also worn them in the tropics and even as a swimsuit( more or less, lol). Great for all- around use, year- round use in all weathers!
5
chupacabra
[ These are super breathable and odor resistant. I originally bought these for hiking and travel and now I wear them everyday, they 're pretty much all I wear. For travel, when you can only take a few pairs of undies and have to hand wash and hang these to dry, I 've found these dry faster than synthetics

[ I got these for winter runs after some tech- fabric athletic underwear I had was causing some pretty bad chaffing. I 've put in about 35 miles with these and love them so far. I 'm also looking forward to using these on an upcoming ski trip, and I see no reason they wo n't be equally effective for that activity. Also, I generally struggle with itchiness when wearing wool items in direct contract with my skin, but have no issues with these.

[ Nobody really specifically reviewed size so here: My size in jeans: ~31( Most) Sweats and athletic shorts: medium Hanes boxer briefs: medium Waist measured with a tape: ~34. 5 '' I ordered medium and they fit perfectly. Large would have definitely been too loose and smalls probably a bit tight but not uncomfortably, and would have just fit more like compression shorts. And they 're light, thin, breathable and stretchy. Ca n't attest to durability yet but construction seems solid, no loose threads, and the waistband is adequately thick. Overall very comfortable.
