Heidrun 2.0 are a pair of lightweight and easy to use down shorts for keeping legs and hips warm during breaks and downtime.

These 800+ Fill Power down shorts end just below the knee and have press studs down the sides, which make them easy to put on and take off. The fit is loose and the closures are adjustable. The hem over the knees is asymmetric, and the knees are pre-bent. The rear and knees are reinforced for durability. A mesh bag is provided for compressed packing, but remember not to store the shorts compressed for long periods. The outer material is recycled polyamide, and the 800+ Fill Power down is bluesign® approved and RDS certified. The Heidrun Shorts are a fluorocarbon-free product.

100% Recycled Polyamide

bluesign® approved fabric

PFOA and Fluorocarbon-free

Polyamide (Nylon) is a synthetic fibre made from petroleum, creating an extraordinarily strong and versatile fabric. We use both post-industrial and post-consumer recycled polyamide.

Post-consumer waste is our first-hand choice since we want to encourage people to hand in their worn products for recycling. Post-consumer waste used for recycled polyamide includes discarded industrial fishing nets, old carpets and rigid textiles.

Recycling polyamide adds another layer of complexity to the production process, but the result is a reliable, long lasting fabric that is lightweight, quick-drying and wind resistant, and uses what would otherwise become waste while saving energy and resources. We were the first outdoor company to use recycled polyamide across our entire backpack line in 2009.


White Goose Down 93/7 (93% Goose Down, 7% Feathers)

Fill power 800+ (IDFB/US method), 750+ (EN12131)

bluesign® approved down

Certified by Responsible Down Standard

At Klättermusen, we use only 800+ fill power goose down of the highest quality as insulation in our down products. Few competitors can match our warmth-to-weight ratio, and our down keeps its shape and insulating properties for decades if taken care of properly. 

All the down we use is RDS- certified (Responsible Down Standard).

RDS-certified means that the entire supply chain is audited, and the welfare of the birds is respected during their entire life cycle. For example, live-plucking and force- feeding of the animals is strictly forbidden and all the down is fully traceable back to the farm.

We have chosen to work with chlorine-free, unbleached down, which means that a few feathers in every down product will be dark. If you encounter a feather visible through the outer fabric, gently squeeze or shake it until the feather has disappeared.
