Mountaineering Waterproof Jacket

A best-selling all-season all-weather jacket developed for mountaineering. This is an updated version of Klettalmusen's best-selling product, which has been loved for 10 years since its launch in 2010. It has become the everyday jacket of Swedish adventurers, offering superior protection in all weather conditions and all types of outdoor activities, while maintaining a great fit and uncompromising functionality.

Made from an original material that does not contain fluorine resin and is stretchy, comfortable, and quiet to use, it has Klettalmusen's unique cutting, making it suitable for everyday use as well as on the mountain. All seams are seam taped. There are plenty of subtle design touches, such as the placement of pockets that don't interfere with the use of a climbing harness. It is also equipped with a Reco avalanche reflector, large mesh hand pockets that also function as ventilation, and a card pocket on the inside of the sleeve.

The fabric is Coutan® 3 layer. With Klettalmusen's proprietary waterproof and breathable technology, we have developed a PTFE-free membrane and are free from fluorine compounds during production, improving both the performance and sustainability of existing fabrics. Developed to improve. It's flexible, has great stretch, and is 100% fluorine-free. The outer fabric is a stretch material that uses a hybrid textile that blends elastane with polyamide made from recycled raw materials, and the lining uses corduroy-patterned polyamide to improve comfort.

Coutan® is a proprietary waterproof and breathable technology developed by Klettalmusen, which has developed a PTFE-free membrane and eliminated fluorine compounds during production, improving the performance and sustainability of existing fabrics. Developed to improve both sex. Coutan® fabric is flexible, has excellent stretch and is 100% fluorine-free. Constructed of 3 or 2.5 layers of membrane fabric, they are highly waterproof and breathable and are impregnated with a fluorine-free, water-repellent impregnant. The membrane is made from polyurethane and is hydrophilic. Coutan® Super Stretch consists of three layers: an inner layer of polyamide, a central waterproof polyurethane membrane and an outer layer of polyamide and stretch fibers. These three layers of fabric are laminated to form one piece of fabric. Coutan® Stretch RP consists of three layers: an inner polyester fabric, a waterproof polyester interlayer, and an outer fabric made from 100% recycled polyester (RP). These three layers of fabric are stacked together to form one piece of fabric. Coutan® Stretch RP is 100% recyclable.

Lower Arms, Hips
Duracoat™ is a unique surface treatment developed by Klettalmusen to improve the durability of high-wear areas. By applying it to particularly vulnerable areas such as shoulders and elbows, it can increase abrasion resistance by up to 5 times. The surface treatment allows it to remain extremely flexible without adding extra seams or layers of fabric. Increased durability without adding weight to the garment or weakening the fabric at the seams. It doesn't distort shape or restrict movement, so it maintains its cut and structure, making it ideal for the agility required by mountaineers. It symbolizes Klettalmusen's tradition of both scientific know-how and innovative thinking.
