The perfect emergency weather protection for your next alpine adventures. The Arc'teryx Alpha SL is an ultra lightweight and packable jacket made of Gore-Tex® fabric with Paclite® technology for breathable waterproof and windproof protection. The jacket provides a helmet compatible StormHood™, WaterTight™ external zippers and a harness Hemlock™ insert.

The Arc'teryx advantage is achieved by merging unrivaled designs with the highest performing materials.

Ultra lightweight weather protection

Designed to be as light and packable as possible, the Alpha SL jacket only weights 305g (9.3 oz) and can easily be stored in its own hood or included stuff sack. Perfect for climbers and alpinists, the fit is motion friendly thanks to the e3D patterning, yet provides a fitted style to enhance breathability, reduce bulk and improve the line of sight towards a harness.

Alpha SL Jacket Features

In order to offer the lightest jacket possible and reduce bulk, Arc'teryx chose a micro-seal allowance of 1.6mm, the narrow Gore® seam tape and the micro corded zipper pulls. All these features contribute in reducing the weight and volume of the jacket without sacrificing its performance. The N40r Gore-Tex® fabric with PacLite® product technology has a mini ripstop construction providing added tear strength without impacting the weight.
