Arc'teryx Alpha SL Jacket - Men's by Arcteryx

Super lightweight, waterproof GORE-TEX Paclite jacket with essential backcountry features and helmet compatible StormHood serves as an easily packable emergency storm jacket in an alpine environment. At 305 g (10.8 oz) this is the lightest alpine hardshell in the Arc'teryx line. Design, materials and build combine to make this the lightest alpine compatible Arc'teryx waterproof shell. The use of e3D patterning technology helps create a jacket that uses minimal materials to create a trim fit with enhanced freedom to move. N40r GORE-TEX fabric with Paclite technology is one of the lightest waterproof/breathable fabric we use. Highly packable, it features a mini-ripstop face for increased tear strength and an exceptional DWR treatment for a high level of initial water repellency. Innovative construction and patterning work with lightweight materials to shed grams. The 1.6 mm micro-seam allowance reduces weight and bulk, as does the use of 13 mm GORE seam tape. Even the zipper pulls use an ultralight cord. An ultralight shell that is all about minimizing weight and bulk without sacrificing advanced performance. It is thoughtfully designed emergency storm protection for fast and light alpine climbing, and works in tandem with the Alpha SL Pant to deliver the confidence to perform even in highly adverse weather conditions.
