Engineered for high-output mountain pursuits, this advanced fleece pullover redefines breathable insulation. It utilizes cutting-edge PrimaLoft® Active Evolve technology with biomimetic construction, replicating the thermal efficiency of animal fur to deliver exceptional warmth-to-weight ratio and unprecedented airflow. Whether you're alpine hiking or trail running in cold conditions, this piece actively manages body temperature, preventing overheating while maintaining core warmth.

Designed for the minimalist adventurer, it is remarkably lightweight and packable, compressing easily into a backpack without bulk. The athletic fit prioritizes performance: a snug, fitted hood seals out cold, articulated thumbhole cuffs keep sleeves in place, and an adjustable hem provides a secure seal against the elements. The interior features an ultra-soft, fast-wicking fleece that feels comfortable against skin and dries rapidly, ensuring you stay dry and focused from trailhead to summit. This is a technical mid-layer built for motion, not fashion.
