The Workout Thong is engineered for movement. Made from moisture-wicking performance fabric, it stays put during high-intensity exercise — running, HIIT, weight training, cycling — without bunching, riding up, or holding sweat. The flat leg elastic seams prevent chafing, and the modal-lined gusset keeps you fresh through tough sessions. Invisible under leggings and gym shorts.

• Style: Mid-rise performance thong

• VPL (Visible Panty Lines): None — invisible under leggings, gym shorts, and cycling gear

• Best For: Running, HIIT, gym, weight training, cycling, Pilates, yoga, hot yoga

• Fabric: 80% Recycled Nylon, 20% Elastane Lycra

• Waistband: Wide, soft self-fabric, no-dig, no-roll

unparalleled performance

Boost your confidence with underwear engineered to be worn under gym leggings

Goodbye Distractions

Experience unparalleled performance with our premium workout underwear, meticulously engineered to stay in place and eliminate distractions. No more rolling or bunching.

Moisture-free

We chose a fast-drying recycled nylon to keep you sweat-free whilst you exercise. Why? Because regular cotton underwear retains moisture when you sweat leading to unwanted infections.

Designed to move

Featuring a 4-way stretch, The Workout Thong moves seamlessly with you, ensuring squat-proof confidence and ultra-comfortable wear both in the gym and every day.

frequently asked questions

Same thong shape, different fabric. The Everyday Thong uses ultra-soft modal designed for daily comfort under work clothes, jeans, and dresses. The Workout Thong uses a moisture-wicking, quick-dry performance fabric engineered to handle sweat and movement during exercise. If you’re heading to the gym, choose Workout. For everything else, choose Everyday.

Yes. The Workout Thong is designed to stay put during high-intensity movement — including squats, deadlifts, running, and HIIT. The flat leg elastics and secure waistband prevent bunching and riding up.

Absolutely. It works for everything from hot yoga to weight training. The moisture-wicking fabric handles sweat, and the flat seams prevent any chafing during floor work and stretching.

If visible panty lines under leggings bother you, or if you find briefs bunching during certain movements, the Workout Thong solves both problems.
