Klättermusen of Sweden is set to release a new range of down jackets made with plant-based fabrics

Klättermusen, which has been making hiking wear in north Sweden since 1984, is set to launch a new range of down products that feature an outer layer made largely from castor bean oil.

The range is created using an innovative new manufacturing process, introduced to lessen the reliance on crude oil for jacket fabrics.

Traditional nylon is based on 100% crude oil. However, with Klättermusen’s fabric, 60% of the crude oil is replaced by oil from castor beans.

Products in the range include the Bore 2.0 down jacket, which has 800+ fill-power down and a 20 denier outer material, and the thinner and slimmer Atle 2.0 which is designed to be worn under a shell. There’s also a down sweater and even shorts.

All of the products have non-penetrating seams, and the down used is 100% traceable and bluesignapproved. Bluesign is an initiative to help eliminate harmful susbstances from supply chains. This year Berghaus became the first British brand to sign up to it.
