Warm at Rest, Cool in Motion
Polartec® Alpha™ Direct 90 fleece fabric is engineered to regulate body heat as your output changes — holding warmth when you stop and releasing it when you're moving. No more stopping to peel a layer.
Crossbody Core Warmth
Strategic crossbody paneling adds the equivalent of 1.5 extra layers of insulation directly over your core, targeting warmth exactly where you need it most on long, cold approaches.
Ultralight + Packable
At just 4.9 oz, this is our lightest midlayer yet. It compresses easily into a pack pocket and works just as well as a nighttime camp layer as an on trail insulator.
Breathable by Design
Alpha™ Direct's open-structure mesh backing means moisture and heat vapor move through the fabric instead of building up so you stay dry and comfortable across a wide range of temps and output levels.
Contoured Hood
A fitted, contoured hood adds warmth and coverage without bulk, staying put when you need it, and out of the way when you don't.
