With its streamlined design and exceptional warmth-to-weight ratio, the Alpha Cruiser™ is our flagship layer. Built for high-output movement and changing conditions. Designed to excel as both a standalone piece and an ultralight midlayer, it delivers impressive warmth while remaining lighter than a typical long sleeve shirt. The soft-touch Polartec® Alpha® Direct fabric breathes efficiently, dries quickly, and keeps you comfortable whether you're pushing miles or just hanging at camp.
