The Nano-Air® is your leave-it-on layer for nonstop, cold-weather pursuits.
Nano-Air® Light
Redesigned with responsive 40-gram FullRange® insulation that keeps you warm when you pause and cool when you push. Twenty-gram FullRange® insulation under the arms helps regulate heat, and a microtextured liner resists sticking to sweaty skin.
Find Your Nano-Air®
The Nano-Air is filled with a responsive, breathable insulation that’s paired with a stretchy, quick-drying flyweight fabric. It’s the versatile slayer layer you never have to take off.
Tuned for Comfort
Our FullRange® insulation captures warmth from your body while allowing excess heat to pass through the outer fabric, adapting to your output for ultimate comfort. The microtextured liner dries fast and wicks moisture away from your skin, so you never feel sticky or clammy.
