Arc'teryx® Gamma Jacket is crafted from durable, comfortable Wee Burly™ Double Weave fabric that resists wind and water, and has excellent stretch. Brushed backer adds light warmth and comfort next to skin. Vislon® front zipper with wind flap and chin guard for added comfort. No Slip Zip™ prevents inadvertent opening. Zippered chest pocket and hand pockets for secure, accessible storage. Finished with FC0-DWR (Durable Water Repellent), it helps repel moisture while maintaining a soft, flexible feel. Articulated patterning enhances mobility, and the high-hip length allows for unrestricted movement on the trail or in the city. A semi-elasticized cuff and adjustable hem drawcord help seal out drafts for a secure, comfortable fit.
