The Gamma LT is made from super tough Burley Weave four way stretch fabric that combines the superior strength & durability of a nylon face with the comfort of microfibre polyester backing. Treated with a DWR (Durable Water Repellent) it will repel light rain & snow, & the tight weave resists wind yet allows excellent breathability. A small amount of Spandex & the way the fabric is woven allows for full four way stretch making this fantastic jacket extremely comfortable to wear. As you would expect from Arcteryx, the Gamma LT is fabulously constructed with simple understated good looks. 4 way stretch Burly Double-Weave fabric Wind & water resistant Breathable Full length Vislon front zip with wind flap High collar 2 x zipped hand pockets Laminated zipped sleeve pocket Stretch gusset cuffs Hem drawcord
