Men's Freelight AOP Polartec Alpha Half Zip

Freelight is Peak Performance's trail/run active-insulation layer, built around Polartec Alpha Direct — 85 gsm open-knit fleece that insulates and breathes at once. That means high-output warmth for running, fast hiking, cool-morning starts, without the clammy feeling of a sealed puffer. Light, quick-drying, partially wind-resistant. Made without intentionally added PFAS. AOP half-zip, same 85gsm Polartec Alpha Direct, lighter pullover cut.
