We strongly believe in creating products that last. Klättermusen was founded in 1984, and we regularly mend and repair clothing products sent in from our users that have been going for 20 years or more. Keprotec Kevlar from Schoeller® is one of the many ways we make our gear last longer, an extremely protective fabric originally developed for motorcycle racing. High-tensile aramide fibers are woven into the fabric, creating an exceptionally durable material that still maintains its elasticity and softness and is bluesign® approved. We use Schoeller® Keprotec Kevlar to reinforce high abrasion areas like cuffs, storm flaps, knees and backpack bottoms.
