Jack Wolfskin shares many attributes with Klättermusen including a focus on sustainability, a similar price range, and an emphasis on outdoor technical apparel designed for durability.

Klättermusen makes technical mountaineering apparel and packs from Åre, Sweden, where a group of local climbers started it as a DIY workshop in 1975. The range spans waterproof shells, down and synthetic insulation, trousers and backpacks, recognizable for off-center zippers, exposed daisy chains and muted Nordic colorways, with recycled fabrics and repairability central to the design brief. Its recent Go Feel Wild hiking collection launched with an 11-minute short film built on Swedish folklore. Streetwear retailers including Sneakersnstuff stock the label alongside outdoor specialists.
