Patagonia R1 Air Crew

Stay warm, dry, and light on your feet when the temperatures drop. The Patagonia Men's R1® Air Fleece Crewneck is a high-performance, technical midlayer designed for high-exertion activities in cool weather. Whether you are backcountry skiing, alpine hiking, trail running, or casting a line into crisp morning waters, this lightweight fleece offers the perfect balance of thermal efficiency and maximum breathability.

Engineered with a unique zig-zag textured knit, the hollow-core yarn construction traps body heat while simultaneously channeling moisture away from your skin. This allows the fabric to dry incredibly fast, keeping you comfortable during intense movement. The classic crewneck silhouette offers a clean, low-bulk regular fit that layers seamlessly under a technical shell or packs away effortlessly when not in use.
