Cloth is more substantial then prior versions, it doesn't feel like it'll tear a hole by just looking at it. It not as soft as the prior version but I'll trade that for much better durability.

Only underwear that I wear

These are the best underwear. For the cost, I wish that they lasted a little longer, but after wearing them, I can't bring myself to wear anything else.

Best Investment

After my first backpacking trip through Denali in 2017, these boxers quickly became a staple. From month-long to four-month road trips, countless hikes, backcountry hunts, and long fishing days, they’ve held up better than anything else in my gear bag. Only now, years later, are they finally showing signs of wear — and I’m genuinely excited to repurchase. Dependable, comfortable, and built for the long haul.

My favorite underwear

Amazing light wool underwear perfect for everyday use as well as in the field and during competitions. Moisture wicking and they keep me warm even when they're wet. These dry super quickly and are my everyday underwear choice.

Very Short Lived

I loved these boxers at first and bought several pairs, but within a year every single pair I owned completely wore out in the crotch. It became a joke with my wife. Has to trash them all.

I got these to try out instead of synthetic boxer briefs, and they are definitely an upgrade. They’ve kept me dry and comfy through many heavy workouts and hikes, and haven’t chafed or started stinking once. I do have one big problem with them, they have a seam that runs right up the butt and pretty much give you a constant wedgie. If they would get rid of that seam these would be the best boxers on the market.

Almost great

The wool is nice and soft but the legs ride up like crazy. Could be my thick thighs but I can’t suggest these.
