Specs Sizing
Most Packable
As weight and space are critical factors in the Alpha SL’s performance, the lightest and most packable GORE-TEX® fabric, N40r GORE-TEX® fabric with Paclite® product technology, is used. Waterproof and highly breathable, the fabric protects from the weather and offers a higher level of comfort during activity. As the Alpha SL is intended for periodic emergency use, a lighter less abrasion resistant face is used to eliminate weight and bulk. However, the fabric has a mini ripstop construction that provides added tear strength without impacting weight.
 
Everything Essential
The Alpha SL’s disciplined design is pared down to the essentials. The helmet compatible StormHood™ delivers full coverage with a secure fit that provides ergonomic performance and exceptional freedom of vision and Hemlock™ inserts help prevent the jacket from riding up under a harness. The Trim fit with motion friendly e3D patterning is designed for mobility, yet keeps the jacket close to the body to enhance breathability, reduce bulk and improve the line of sight towards a harness.

Excellent, no pockets, no pit-zip jacket

Lightweight, very packable, this jacket hides well in the bag. But its truly minimal. Thus, for those of us who like using pockets - for food, gloves, maps, or whatever - take note: there's only one Napoleon (though very roomy). And for those who like pit-zips (remember: zippers = weight), this is not your jacket, either. So, there's a reason for the feather-weight, and a price as well. The rest is Arcteryx, including smart features to leave it below the harness (or backpack). Nicely done.
