Mountain INS Hooded Jacket 10M

The Mountain INS Jacket 10M is warm, packable, and breathable, perfect for layering in cold conditions or as a standalone piece.

This insulated jacket is water-resistant with lamination, but not waterproof. Using 80g featherless Sorona® insulation, we create warmth without using any nature-damaging components and partly biobased materials.

Key features include SBS™zippers, a packable design, an adjustable hem, and 4 pockets. The jacket has elastic bindings and embroidered logos.

Thanks to customer feedback, the Mountain INS Jacket 10M now has the perfect fit and added lamination for increased water resistance. The Regular fit ensures unrestricted movement and accommodates one extra layer for added warmth.

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.
