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.

• To care for your DWR-treated jacket, wash it with a special technical detergent (like Nikwax) in a front-loading washing machine on a warm setting with an extra rinse cycle. Avoid using standard laundry detergents, fabric softeners, or bleach, as these can interfere with the DWR coating.
• Tumble dry the jacket on low with warm heat for at least 30 minutes to reactivate waterproofing.
