Super lightweight and compact, the Arc'teryx Alpha SL Jacket is a waterproof jacket constructed using GORE-TEX® fabric with PacLite® product technology and designed with essential climbing features such as a helmet compatible StormHood™ and Hemlock™ harness blocker; ideal as a packable emergency storm jacket for alpine or multipitch climbing.
Patterned using e3D technology for a trim, clean, climbing friendly fit, and pared to only essential features, the design, materials and build make this the lightest Arc'teryx waterproof shell.
N40r GORE-TEX® fabric with Paclite® technology is one of the most compact waterproof/breathable fabrics that also meets Arc’teryx standards for durability for its intended use. Highly packable, it packs into its’ stuff sack taking up less than 1L of space and can be clipped to your harness for quick access while climbing.
Innovative construction and patterning work with lightweight materials to shed grams. The 1.6 mm micro-seam allowance reduces weight and bulk without sacrificing strength, 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.
