The Sigyn Half Zip by Klattermusen is a warm, soft and comfortable bio-based mid layer made for alpine climbing and mountaineering.
It can be worn under a shell jacket or as a standalone piece and also works perfect for hiking and trekking. It’s made from 100% PLA to create a super light and soft fabric that is biodegradable, naturally antibacterial and is made of 100% corn starch. The sweater features a front zip that is slanted to the side with a chin guard to avoid chin abrasion. The shoulders, chest and top sleeves are one continuous piece to get full use of the flexible and soft fabric. For safety we have also added reflective triangles at front and back and the seams are moved towards front to avoid abrasion.
The fit is standard so order the size you usually wear.
Machine wash on gentle cycle at 40°C. Do not iron, bleach, tumble dry or dry clean.
