Nice but really small

Unfortunately, these ran really small for me -- I ordered a size M (which is what I usually wear in boxer briefs) and they were really small. They were also small (tight around the thighs) for my partner, who usually wears a women's M in underwear. She'll make them work and they seem like nice quality - maybe there's some stretch to be discovered.

Awesomely durable & comfort lasting

Ok, try not to shriek but wore my briefs on an 8 day trip without washing! I know are you nuts. Hey I chaff so bad in other materials, but these even vanquished my prior irritation - they actually healed me! Only thing they are hardly stocked and I want to buy a 3 pack for my AT thru in April of 24

Excellent Briefs

So far so good. I like the waist band as it is elastic and gives a snugger fit. The briefs are made with the right amount of material so they are not baggy but are form fitting and keep things contained. I washed a couple of times and no problems. I have other wool underwear, made of Merino wool. After a couple of years the merinos begin to run and break down. Too early to tell whether Alpaca will do the same thing. Alpaca, the fiber, tends to sag or stretch out over time. I’m waiting to see how Arms of Andes’ Alpaca does.

Good vibes 😎

Smooth, functional and easy to wear. Will probably order a few more in the near future.
