For ultra-distance races, mountain efforts, and extended trail sessions where storage, durability, and composure matter equally. When the terrain roughens, pace holds, and elevation stacks. When the mind narrows and the body must follow. For demanding efforts in any season. 

Rippy™ Cordura® Shell - An ultra-light ripstop woven fabric developed in Japan, reinforced with Cordura® fibers for enhanced abrasion and tear resistance. Fast drying with 4-way stretch to follow natural stride across technical terrain

TechSilk™ Drift Brief Liner - Our proprietary performance fabric engineered for remarkable comfort: ultra-light, silky hand, high resilience, and exceptional breathability. It dries astonishingly fast to limit odor build-up and stays comfortable at high output. Developed in-house and produced by a heritage elastic specialist, TechSilk™ Drift blends medical-grade insight with running intent. Durable, breathable, and fluid in every direction.

TechSilk™ Evo with Coldblack® - Italian high-recovery knit engineered for cooling performance and UV protection. Coldblack® technology reduces heat absorption and enhances thermal regulation in high-exposure environments.
