The Arcteryx Alpha SV Jacket is the ultimate Gore-Tex waterproof mountain shell providing the toughest of barriers against the severest weather. With a roomy expedition cut the Alpha SV is designed to allow freedom of movement even when you have several layers of clothing underneath.
Gore-Tex Pro is the toughest and most durable waterproof fabric in the Gore-Tex range. It has been constructed for intense activity that may include frequent stops providing the high levels of breathability required by the climber, mountaineer or ski tourer.
The jacket is secured with a tough Watertight Vislon zip, these heavier zips are easier to use especially with gloves on. The helmet compatible storm hood can be drawn in with just one hand battening the hatches down. But if the weather is poor and you're working hard ventilation can be provided by through the underarm pit zips. On either side of the hem is a HemLock insert that holds the jacket comfortably under a climbing harness and prevents it riding up.
