Built for demanding backcountry missions, the Heyburn Jacket is a lightweight 3-layer shell designed with a streamlined, function-first approach. A 30k/30k waterproof and breathable membrane delivers reliable storm protection without unnecessary bulk.
The proprietary fabric pairs durability with a soft hand feel and advanced thermal regulation, enhanced by a NASA-developed Trizar® internal backer. With light mechanical stretch and an ergonomic, women-specific fit, this jacket moves easily uphill and downhill while staying pack-compatible and distraction-free.
