"SL" means "superlight", which might be the first thing you notice about the lightest waterproof breathable shell in the versatile Beta series from Arct'teryx. You might also notice how full-featured and well-built this jacket is for its weight. Ideal for fast-and-light hiking or as an emergency shell on multi-pitch climbs, its packability also makes it a great choice for backpackers and travellers. A fully adjustable storm hood, drawcord hem and cuff adjusters offer complete protection from the elements, while underarm vents keep you comfortable when you're on the move. The front zip, vents and pockets all feature top quality water-resistant zippers and the overall build quality is top-notch, with tight seam tolerances and articulated construction that accommodates any move you need to make.

Fabric waterproof rating
The standard test for waterproof fabrics uses a standing column filled with water. The figures given are the water column height. A rating of 3,500mm or higher can be considered waterproof. The higher the rating, the more durable the waterproof fabric will be over time.
Waterproof garments use waterproof-breathable technologies and are fully seam-taped. Water-resistant garments use waterproof-breathable technologies but their seams are not taped. Water-resistant garments repel water and protect against wind but are not made of waterproof fabric.

Fabric active breathability
The rate at which a waterproof breathable fabric expels moisture when the inner surface is moist from perspiration. Values under 8,000g/m2/24h provide low performance, 20,000g/m2/24h provide moderate performance and values over 30,000g/m2/24h provide high performance.
|Pockets||2 front zippered|
A windproof garment does not allow any air to permeate the fabric. A garment with windproof panels has panels of fabric that are totally windproof, but the rest of the garment may not be windproof. A wind-resistant garment resists some wind, but not as much as a garment that is windproof.
Durable water repellency
Usually referred to as DWR. A treatment made to fabrics that causes water to bead and run off instead of soaking through.
