The incredibly versatile Arc'teryx Men's Kyanite Fleece Jacket is an ideal option for everything from climbing big walls in the fall to scoring epic powder days in spring.

Polartec Power Stretch Pro traps heat and stretches effortlessly to keep up with your movements when you're skiing, hiking, or climbing. It manages moisture to keep heat-robbing moisture from leaving you cold and clammy, and it also breathes exceptionally well to keep you from overheating during arduous ascents. And don't worry about the occasional brush with granite or bark—a nylon face adds abrasion-resistance for extra dependability. The hand pockets sit high on your torso so you can access them while wearing a backpack or harness.
