Stretch Your Story (SYS) introduces the ButterMelt™ Legging, a hero style that represents the core values of the essential collection: a true second-skin fit, refined construction, and total presence in motion. Precision-engineered in Korea at the SYS Fabric Lab and infused with LYCRA® ADAPTIV technology, ButterMelt™ moves intuitively with the body — stretching where it is needed and gently holding where it matters most.

Ultra-light and cloud-soft, the fabric delivers a barely-there feel without sacrificing structure. It glides smoothly over the skin without digging in, chafing, or restricting motion, allowing wearers to stay focused on breath, alignment, and form. The result is a true second-skin experience designed for yoga, Pilates, and recovery — where comfort and connection are as important as performance.

“ButterMelt™ uses fiber engineering to support the body through motion, rather than relying on tight elasticity for compression. The material responds in real time, making it ideal for deep stretches, controlled poses, and moments of stillness,” said a fabric engineer at the SYS Fabric Lab. “ButterMelt™ was created to disappear on the body. It moves with breath, not against it — giving support through softness and structure without weight.”

Breathable and refined in silhouette, the ButterMelt™ Legging is designed not just to perform, but to help the wearer feel fully present in every movement. It reflects SYS’s belief that performancewear should enhance awareness as much as it enhances motion — connecting body and mind through intelligent, understated design.

STRETCH YOUR STORY (SYS) is a performancewear brand Precision-Engineered in Korea. Founded on the belief that movement begins with intention, SYS combines textile innovation with design integrity to create performancewear that moves like a second skin and performs with precision.
