Mountain INS Jacket 7M

The MNT Insulated Jacket 7M is warm, packable and breathable. Perfect for layering in cold conditions or as a standalone piece. This insulated jacket is water-resistant, but not waterproof.

Using 80g featherless Sorona® insulation, we create warmth without using any nature-damaging components and partly biobased materials. Featuring details of elastic bindings and 5 pockets.

Thanks to customer feedback the MNT Insulated Jacket 7M (formerly known as the Mountain Mid-layer) now has the perfect fit and increased sleeve length for extra comfort.

We've carefully balanced functionality and performance. We carefully selected a wide range of features to help realize this. Key features include - but are not limited to - 5 essential pockets, YKK zippers, packable design and adjustable hem.

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.
