Bought 2 pairs for 10-day backpacking trips to Alaska. Wear a pair and wash out the dirty one by the river at the end of the day. They dry in a flash, even in 30 degree overcast weather. They fit comfortably and never ride up.

I forgot my beanie on a recent high altitude climb. My girlfriend suggested me wearing these to keep my head warm. They looked a little ridiculous but did work. No joke dudes & dudettes. Multi-utilitarian clothing at it's best.

I wear them almost every day. Need I say more? I am 5'6", 120 lbs...size small is perfect. Whether climbing, hiking, camping, sleeping, working, whatever...these are great.

True to size. Probably the most comfortable brief I have ever worn. They also do not "ride" anywhere and stay put on the most difficult hikes.

its not a thong but if fits well enough if you dont mind feeling like you are wearing a garbage bag. i go for a minimialist wrapping, and this one was true to size and didnt ride up, but sometimes i prefer if things lifted and separated....

Hands down the best wicking undies I have ever worn. I became addicted about 2 years ago and I have been unable to hike, run, bike, climb, etc. in any other pair of underwear ever since. They are super comfy and the most important thing is that they really WORK!

waay cute. I wear these all the time and they don't ride up :)

I brought a pair of these and some other pair on a 40 day trip in the Himalayas and this pair was amazing. They are easy to clean, dry fast and so comfortable. I love them!

The Patagonia Active Briefs are honestly the best underwear that I've ever worn. I love the full butt coverage (which doesn't look granny-ish) that keeps them in place during any activity.

I have several pair of these. They are comfortable and wear well even after many, many washings. Especially great for travel as they dry quickly.

Patagonia undies are the best. They are great for sports, smooth and sleek under your clothes. Capilene is quick dry (if you fall in while paddling) and the colors are fun.

Love these undies. Like wearing nothing, which is what I did until I found these. Wish they didn't run out of the cool pattern so fast!

I love the active briefs. I wear them everyday. So comfy, stylish, no lines...perfect.

No seams. No panty lines. Ultimate comfort. Feels like I'm not wearing them! Also, very light weight, so they dry quickly. I hesitated on the price, but so far think they're worth it.

I bought some of these for a backpacking trip and have been wearing nothing but these ever since. They cover your whole butt (a little weird at first) and don't move anywhere - no matter how active you are. When backpacking, they are really easy to wash in a stream, and dry in no time.

These are great! I hiked the Inca trail a few weeks ago and rocked these babies for a most of the time out there. They fit well, work excellently hiking, and are super cute too! Patagonia makes excellent products, right down to the undergarments. I really love them!
