Sports-Hiking Camping
"I wear these at the gym and hiking. Great support and the fabric is very comfortable." -Matthew W. Briefs Polyester REG
"These briefs feel great and are perfect for running and hiking!" -Matthew J Briefs Bamboo REG
"Great fit - I use mainly when doing moderate distance cycling in the city and hiking. I bought the 3.1 and my only slight recommended improvement is to shorten the waist strings a bit. Even when the pouch is fully uncinched, there's quite a bit of string to deal with and make sure it's tucked into the gym shorts. I'm a 30-31 waist generally, and the M fit perfectly, btw." -Ken L 6" Polyester MAX
