Heyburn 3L Jacket

The Heyburn Jacket is a high-performance and lightweight, 3-layer (3L) shell engineered for demanding backcountry conditions and needs, featuring a 30k/30k waterproof and breathable membrane. Designed with a streamlined, function-first approach – no hand pockets so it can be easily worn with a pack and no bulky powder skirt - it utilizes a proprietary fabric that optimally balances durability, a soft handfeel, and advanced thermal regulation—enhanced by the NASA-developed Trizar internal backer. Light mechanical stretch ensures unrestricted mobility, while the ergonomic, feminine silhouette delivers a precise fit and won’t hold you back—on the uphill or downhill
