DescriptionSigyn is a lightweight, warm and flexible bio-based fleece midlayer for alpine mountaineering. It can be worn under a shell jacket or as a standalone piece during more active use.
The Sigyn Hooded Zip Jacket is constructed using a 100% PLA fiber made from corn starch to create a super light and soft fabric that’s fully biodegradable which avoids micro fibres staying nature. In addition it is naturally antibacterial. It features a slanted zipper to avoid chin abrasion, a snug-fitted hood that fits perfectly under a helmet, and two hand pockets that are placed higher to work with a harness or backpack.
