Best for: running, training, and high-intensity workouts.
Our award-winning Seamless Thong is built to keep up with running and training days — incredibly fast-drying, no ride-up, and no chafing, so it doesn't slow you down mid-workout. All-day comfort and confidence, with no visible lines under leggings or activewear.
Exceptional Comfort: Seamless design with no annoying tags, made with super-soft micro denier nylon and spandex yarns.
High Performance: Wicks moisture and dries quickly through a run or training session. 4-way stretch fabric moves with you, offering unrestricted freedom of movement.
Durability and Quality: Our thong is BPA and PFAS-free and constructed from high-quality materials that are built to last.
Stay-in-Place Promise: With our stay-in-place promise, you’ll never know it’s there.
Note: our seamless thong runs small. Size up if you are in between sizes.
