REI Co-op  Active Thong Underwear - Women's

I've worn these twice, once for a normal day around the house and again on an afternoon trail hike with my dog. So far they feel pretty great! I was skeptical when I first got them because they're very lightweight and don't have a cotton liner (it IS lined, but it's the same sport fabric as the rest of the thong). The outer seams have this thin elastic edging sewn on which I assume helps it lay flat, but I'm anticipating it stretching out and ruffling at pressure points based on experiences with similar fabric types. All that said, while they aren't super high end, they are very very comfy and fit surprisingly well without pinching or gapping. Worth the money if you want a versatile easy-care thong.

Great balance of a nice pair of underwear for high sweat activities and a lot price point compared to a lot of other active underwear. I have 5 of the thongs and maybe 12 of the bikini style pairs. I know other people have mentioned fraying seams, but thats only happened to one of my pairs so far and I've been wearing these as my every day and active underwear for at least a year now. I wash them on the delicate cycle and try to hang them to dry, but I definitely don't always remember to do that. Plus, I wore these on my JMT week long hike, they wash up and dry like a champ hanging from the back of my pack.

These are my favorite; they dry quickly and so comfortable you hardly know they're there. HOWEVER, they are never available in size small or medium. WHY? Please add more stock for smaller people.

I bought one pair to try out. I ended up loving these but never in stock in my size (M-L)

The best underwear for athletic endeavors and day to day alike. Whenever these are available in my size I grab a few. I just wish they had them more available.

Love this thong and have it in the "Active fabric" as well as the Merino. I was concerned at first that it wouldn't stay in place as there is no elastic at the top of the band but it Stays right wear I put it and doesn't shimmy down when hiking- Working out or doing Yoga. I stopped wearing all my other active thongs

These are my go to panties for hiking and traveling and everything active. They’re so comfortable that I forget I’m even wearing them. Please bring back smaller sizes!!

I absolutely love these thongs the fabric texture feels like you’re not wearing anything but protected. They are thin enough but enough fabric to cover. I’ve tried other thongs saying for high fitness sweaty activities from REI and Victoria’s Secret but they don’t compare to these thongs. The band doesnt dig in like others are too thick. They have washed and held up so well traveling I’ve just put some dish detergent and washed the crotch and hung them up to dry hardly feels wet bc of the material. My measurements waist is 25 inches and hips 33 inches and got a small. I weigh 110-112 height 5’2”. I wear these under tight fitting dresses and no lines so not just for sporting activities

I love this underwear, they're extremely breathable and comfortable. I've had several pairs of these for years and they've lasted. When are they coming back??

I liked this underwear, but after a few washes the stitching quickly started unraveling on both pairs that I bought.
