Ideal For & Trail Performance:

• Winter Camping & Bushcraft: Once active hiking stops and camp chores begin, your body temperature drops rapidly. The 90% duck down inner jacket traps body heat instantly. The fixed, fully adjustable hood creates a complete wind barrier around your head while working around the campsite.
• Extreme 3-Season Trekking (Spring, Autumn, Winter): Designed for changing wilderness climates where it snows in the morning and rains in the afternoon. The 10,000 g/m² breathability keeps you dry from the inside out during uphill ascents, while the 10,000 mm membrane keeps severe dampness away.
• Exposed Mountain Trails & Ridge Hiking: In areas above the tree line where heavy winds blow, shorter sports jackets let cold drafts slip underneath. The extended length of the 48C851A-5 combined with Velcro cuffs seals your body inside a protective windproof capsule.
• Coastal Walks & Everyday Winter Utility: The timeless olive green tone and sleek silhouette transition effortlessly from technical woodland trails to harsh urban commutes and long weekend walks along windy coastlines.

Care Instructions

• Outer Shell: Machine wash cold (30°C) on a gentle cycle using liquid membrane cleaner. Do not use fabric softeners (softeners damage the DWR coating and reduce breathability). Line dry.
• Inner Down Jacket: Close all zippers. Wash separately on a dedicated down cycle. Tumble dry on low heat with 3–4 clean tennis balls to fully restore the loft, fluffiness, and uniform distribution of the duck down velvet. Do not iron. Do not dry clean.
