Hiking, climbing, or skinning uphill—the Gamma Hoody keeps you moving through rugged terrain. Weather-resistant fabric and a helmet-compatible StormHood™ shield from the elements while maintaining max breathability on that final summit push. Stretch material makes overhead movements a breeze, and durable face fabric stands up to rough scrambles.

What's been updated: Updated with increased recycled content and a FC0 DWR (Durable Water Repellent) treatment that’s free from intentionally added PFAS. Two zippered chest pockets provide added storage, while the single-point hood adjuster makes it easier to fine-tune your fit. Revised design lines create a more streamlined fit.
