Essential winter gear

"Named for a classic 34-pitch route in the Bugaboos, and designed for moving rapidly in the mountains. The fleece is extremely lightweight and has the features of a true mid-layer. When you're working hard, you can shed your outer layer and the high air-permeability allows the wind to carry off heat and moisture, so you don't get soaked with sweat. When you start to cool down, pull on a shell jacket without feeling all bulked up, and the fabric continues to transport moisture vapour out and away."
