Nunatak INS Ski Jacket

The Nunatak INS Ski Jacket combines 50.000 mm+ waterproof protection with windproof 3-layer Barrier CT Pro™ fabric to keep you protected while skiing and snowboarding. The face fabric is made from 100% recycled material and designed for long-lasting performance.

80g Featherless Sorona® insulation, made with 37% biobased renewable content, provides dependable warmth without unnecessary bulk. It dries quickly and continues to insulate even when damp.

Everything else is built around comfort and control on the mountain: armpit ventilation zippers help release excess heat, while a removable snow skirt, helmet-compatible adjustable hood, and five essential pockets give you practical protection when conditions change.

The Regular Fit leaves enough room for up to two layers underneath while giving you freedom to move.

Care Instructions:

Close all fastenings before washing. Use a gentle cycle at 30°C. Avoid bleach, chemicals, and fabric softeners. Tumble dry on low heat and iron at a low temperature if needed.

Our technical fabrics are designed to perform; fabric softeners interfere with their breathability and water-repellent properties, so skip them.

For insulated pieces, tumble dry separately on low heat with a few tennis balls to help restore the loft. No dryer? Give the garment a good shake and gently redistribute the filling by hand.
