Gamma Jacket Men's is a weather-resistant shell jacket designed for climbing, trail and rock activities, helping block wind and light moisture while maintaining breathability during movement.
Allows moisture vapour to escape, helping regulate temperature and elevating comfort inside garment.
Air permeable four-way stretch woven textiles with superior abrasion resistance.
Pair it with mens hiking pants and a beanie for hiking and mountain days.
Hiking, climbing, or skinning uphill—the Gamma Jacket keeps you moving through rugged terrain. Wind-resistant and water-repellent, it shields from the elements while maintaining max breathability on that final summit push. High-stretch material and articulated patterning make overhead movements a breeze, while 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 revised design lines create a more streamlined fit.

Layers are the instruments of keeping you dry, warm and using your energy efficiently. Put into the right systems, a good sequence of layers provides you with weather protection, moves moisture away from your skin, conserves or dissipates heat, and does this in the least amount of time.
Use the layering guide to select additional pieces for your system and understand how they fit together. Find out more about how to layer on our Layering Page.
