Aero 01 Ultralight Shell

The EP Lite Shell is engineered for peak performance where speed and minimal weight matter. Crafted with premium Japanese Toray Dermizax® 20D fabric, this jacket delivers superior strength without the bulk, designed for dynamic movement and rapid ascents.

Empowered by the highly technical Dermizax® non-porous membrane, it boasts an exceptional $20,000\text{mm}$ waterproof rating and a $20,000\text{g/m}^2/24\text{h}$ breathability rating. This PFC & PFA free shield keeps you completely dry in downpours while offering unparalleled airflow, preventing moisture buildup during high-output activity.

Its 20-denier construction ensures an ultralight, packable design with surprising resistance to tears, making it the perfect emergency shell or fast-and-light mountain gear. Features include an ergonomic, articulation-focused cut, a low-profile, helmet-compatible hood, and a precision-engineered multi-pocket system.

From trail running and speed hiking to volatile alpine conditions, this is the streamlined outerwear built to be felt less, and perform more, allowing you to move fast and push your limits.
