Built for resort skiing and slackcountry exploration, the Sentinel AR takes the advanced fabric technologies and meticulous design common to all Arc'teryx shells and incorporates snow-specific features and a modern, relaxed fit. Long underarm vents let you dump heat during high energy chair laps and bootpacks, while the roomy fit accommodates multiple layers for cold descents. A warm flannel backer provides additional insulation against icy blasts on the chairlift. A fully adjustable storm hood, drawcord hem and cuff adjusters offer complete protection from the elements, and the front zip, underarm vents and pockets all feature water-resistant zippers. 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.
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.
