Arc’teryx Alpha AR Pant Women’s


The Alpha AR Pant brings about lightweight, packability, durability and exceptional weather protection altogether. Updated with GORE-TEX Pro N100p-X for hardwearing performance, superior breathability and outstanding rain and snow protection. The Alpha AR Pant combines all-round alpine performance and protection with a regular fit and features geared for the demands of climbing. Arc’teryx Ergonomic 3-Dimensional (e3D) patterning crafts the shapes of the parts in key joint areas for an added level of use-specific articulation. A unique internal LegWrap™ streamlines the cuff to minimize crampon snags when walking and is removable when not needed. Redesigned to include full length separating WaterTight™ side zippers and adjustable, removable suspenders for drop seat functionality.
