Setting a standard for light, durable protection, the Alpha is made for confident travel in rugged, unpredictable alpine environments. Made with waterproof, windproof, breathable 3L GORE-TEX with our ultralight, ultra-durable Hadron® LCP (Liquid Crystal Polymer) grid face fabric, the Alpha’s abrasion resistance rivals pants made with much heavier materials. The innovative waist cinch holds fast and rides easily under a harness or hipbelt, and full side zips make on-and-off easy.
Our classic fit is cut comfortably throughout the chest, waist, hip, and thigh. It allows freedom of movement, provides shape, and layers comfortably under our regular and relaxed fit shells.
Note: If your measurements are between sizes, select a larger size for a looser fit or a smaller size for a tighter fit.
Several models of Arc'teryx pants are sized numerically and may be available in different inseam lengths. Please refer to the specific product page to see which waist size and inseam lengths are available for your product.
*For all other pants available in numerical waist sizes where the inseam length is not specified, these following inseam lengths apply.
Note: Calculate your own body measurements, then select your product size.
1. Waist: Measure around your waist at the narrowest part.
2. Hip: Standing with feet hip width apart, measure around your hips at the widest part.
3. Inseam: From a standing position, measure from your crotch down the inside leg to the floor.
Cut snug to the body through the entire garment to enhance moisture management and thermal efficiency.
Cut slim to the body through chest, waist, hip and thigh for a low profile fit.
Cut comfortably from the body through bust/chest, waist, hip and thigh for a classic fit.
Cut loosely through the waist, hip, and thigh for a casual fit.
Layers are the instruments of keeping you dry, warm and using your energy efficiently. Put into the right systems, a good sequence of layers provides you with weather protection, moves moisture away from your skin, conserves or dissipates heat, and does this in the least amount of time.
Use the layering guide to select additional pieces for your system and understand how they fit together. Find out more about how to layer on our Layering Page.
