More details Right

The TOURA Thong is our swim-friendly thong hiking underwear designed for any activity. Basewear Bottoms will become the only underwear you need to pack when you head out for travel, backpacking, or just a weekend camping trip. They're quick-drying, light, and comfortable and they won't slip down if you happen to jump off a cliff into a big alpine lake.

PS: We keep saying women's hiking underwear for SEO purposes, but Basewear Bottoms can work great for gender non-conforming, trans, and non-binary folks as well.

Members are saying
“Took a chance on becoming a member before I'd even tried out any TK Basewear, and I'm already loving it. I received my first set quickly after joining and immediately tested the bra out on a run — I have never worn such a comfortable sports bra! Can't wait for the next batch to arrive!”

Members are saying
“The membership is a great deal. You get your money's worth with the initial shipment and early access is imperative because they sell out so fast!”

“This is an amazing way to support a fabulous company. I love getting the pre-order and being able to choose which items, if any, to purchase. I also really like the concept of funding the production of the order and helping to reduce an abundance of surplus or waste.”

FAQ:

I'm in between sizes, should I go up or down?

Measure your perfect fit at www.terakaia.com/find-my-bottoms-size . If you are in between measurements, pick based on your preference! Do you like a breathable fit or a snug fit?

Will my Thong and Brief sizes be the same?

Possibly. If you have an especially curvy frame and your waist size is dramatically different from your hip size, then you may be a size down in the Thong, as compared to the Brief.

Is it REALLY comfy for outdoor activities?

Yes, as comfy as you can feel with some fabric between your cheeks! We've tested the TOURA Thong swimming, hiking, biking, camping, you name it. It really is the best thong ever. If you're not a thong wearer it may not be for you, but if this is your style the TOURA Thong will blow all your other thongs out of the water (pun intended)!
