Best for: running, training, and high-intensity workouts.
MARATHON SERIES Limited edition drop!
Our best-selling Seamless Bikini is now available in marathon colorways! Like our original seamless bikini, it is built to keep up with running and training days, with fast moisture-wicking and quick dry time so it doesn't hold you back mid-workout. Combines high-quality materials with innovative features for maximum comfort and durability.
Superior Comfort: High-quality soft elastic at the leg openings prevents bunching or chafing during movement.
Performance-Driven Design: Made from super-soft, micro denier nylon (94%) and spandex (6%) yarns for 4-way stretch. Wicks moisture and dries quickly, keeping you cool and dry through training sessions or competition.
Innovative Construction: Our Seamless Bikini features no side seams and no annoying tags.
Note: For those concerned about underwear lines under leggings, we recommend trying our thongs.
It's built for running, training, and high-intensity workouts — fast-drying, moisture-wicking, and designed to stay in place during movement.
Yes, plenty of customers wear it daily. It's just optimized first for performance during exercise.
The seamless construction has no side seams, so it sits smoothly under fitted leggings and workout gear. We can’t guarantee a no-show design because there is elastic at the leg openings so it just depends on how it fits you and what you’re wearing over it. If you are looking for no visible panty lines we always recommend our thong collection.
Our Seamless Bikini runs small. We recommend sizing up if you're between sizes.
Our products undergo third-party testing and are certified BPA-free and PFAS-free. Learn more on our blog.
Super comfy underwear that moves freely with you in all directions.
