Our Story

The Foundation of Fitness

At The Gym String, we believe that peak performance starts with the right foundation—underwear that moves with you, not against you. Designed to be invisible yet indispensable, our gym underwear is engineered for maximum comfort, breathability, and support.

Born from a frustration with visible panty lines (VPLs) and discomfort during workouts, we set out to create a seamless, high-performance solution that lets you focus on your form—not your underwear.

Engineered for Performance

Every rep, stride, and stretch matters. That’s why The Gym String is crafted with cutting-edge fabric technology to keep you cool, dry, and supported. Our moisture-wicking, ultra-lightweight materials ensure breathability, while our ergonomic design eliminates distractions—so you can perform at your best, every single time.

And for those who won’t let their period hold them back, we’ve created The Gym String Period Edition—leak-proof, odour-resistant, and ready for even the heaviest days. No leaks, no limits.

Designed for Confidence

Forget about underwear lines, discomfort, or the stress of choosing the right pair for the gym. Whether you're lifting, running, stretching, or cycling, The Gym String stays invisible under your activewear while providing the ultimate support.

Our Commitment

We don’t just make underwear—we innovate for real athletes, gym-goers, and active individuals who demand the best from their gear. Sustainability matters too, which is why our reusable period range is designed to reduce waste without compromising on performance.
