SYS’S PROPRIETARY FABRIC: BUTTERMELT™

This new set is designed as a core style within the ButterMelt™ line—engineered for fluid, second-skin movement. Developed through extensive testing, the fabric delivers a barely-there feel with adaptive stretch that follows the body naturally. It is exceptionally soft without losing structure, and breathable without compromising resilience. The result is a fabric that supports movement without interruption.

LAYERED BRA — BALANCE THROUGH CONSTRUCTION

ButterMelt™ Layered Bra introduces a dual-layer structure, inspired by the signature ButterEase™ design. As one of SYS’s most recognized styles, the ButterEase™ Layered Bra remains a core silhouette—known for its iconic layered construction that balances support, breathability, and refined design.

The new ButterMelt™ version builds on that foundation, maintaining the same layered structure while enhancing the barely-there feel. Updated back straps and a lighter construction create a more open, unrestricted experience. An inner layer, made with a ribbed texture, provides support. The outer layer, smooth and soft to the touch, refines the silhouette. Together, they create a balance between coverage and lightness. Higher armholes, an open-back design, and minimal straps allow for freedom of movement while maintaining a secure fit.

PERFORMANCE JACKET AND BUTTERMELT™ LEGGINGS

The ButterMelt™ Jacket follows the same principle. Lightweight and body-skimming, it maintains alignment through movement with features such as a soft high neckline and thumbhole sleeves.

Vital Vermilion Set

Paired with SYS ButterMelt™ leggings—designed with a seamless front and curved waistband—the system supports fluid, uninterrupted motion. Layering is not treated as styling, but as structure. Each piece is designed to function independently, but also to work together—adapting across low-intensity training, transition, and everyday wear.

Through this new drop, ButterMelt™ continues to define movement not as a single action, but as a continuous flow.
