THE ERGONOMICS OF E3D
Ergonomic fit is a key Arc’teryx design detail. True freedom of movement is not achieved by adding excess volume or space, but is the result of careful utilization of ergonomically planned articulation designed to move as the body moves. Arc’teryx Ergonomic 3-Dimensional (e3D) patterning crafts the shapes of the parts in key joint areas to bring a remarkably efficient level of articulation that provides the Alpha AR’s exceptional, purpose specific range of motion.
PURPOSE DRIVEN FEATURES
The Alpha AR is a climber’s jacket, and features are selected to meet the alpine environment. Easily accessible crossover pockets sit high and work with harness and packs. The full coverage helmet compatible StormHood™ cinches tight, moves with the head and provides exceptional peripheral vision. Removable HemLock™ inserts keep the jacket in position while in use with a harness. Pit zippers add ventilation, and laminated WaterTight™ zippers help seal out weather.
MORE STRENGTH, LESS WEIGHT
Reliability comes from selecting the best materials. N40p-X GORE-TEX® Pro 3L has a high tenacity nylon face fabric that leverages a flat filament warp yarn and false twist textured fill yarn to provide excellent initial water repellency. Backed with a micro- grid woven backer, this waterproof/breathable fabric is notably lightweight and durable. The N80p-X GORE-TEX® Pro reinforcements at the shoulders, forearms and cuffs are specifically placed to protect areas exposed to high levels of abrasion. Strategically mapping these reinforcements allows Arc’teryx to deliver a jacket with longwearing performance and protection that weighs a mere 385 grams.
