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.
