Designed for adventures in the mountains year-round. This breathable midlayer made from Polartec Power Stretch fleece keeps you warm even at high altitudes, and to prevent you from cooling down too quickly at the summit, the moisture-wicking material regulates your body temperature. Thumb loops ensure a secure fit under a jacket. The higher-positioned pockets provide easy access to your gear when wearing a climbing harness or backpack. This makes the Taiss ML Jacket the ideal midlayer, whether you're ascending or descending.
