Versatile, lightweight, hardwearing GORE-TEX® Pro pant for climbers and alpinists. Alpha Series: Climbing and alpine focused systems | AR: All Round.
DESCRIPTION
The Alpha AR Pant hits the sweet spot where light weight, packability, durability and exceptional weather protection come together. The GORE-TEX® Pro N80p-X body combines hardwearing performance and superior breathability with outstanding rain and snow protection. A heavier duty N155p-X material is used where reinforcement is necessary. The athletic fit is streamlined, but leaves room for layering. The Alpha AR Pant combines all-round alpine performance and protection with design and features geared specifically for the demands of climbing.
HARDWIRED FOR CLIMBERS

Streamlined and purpose focused minimalist design includes specific features that are hardwired for 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 removeable when not needed. WaterTight™ side zips add ventilation, highly abrasion resistant Keprotec™ material protects the insteps, removable suspenders add security, and the thoughtfully designed waist belt has a low profile that fits perfectly under climbing harnesses and pack hip belts.
SPINNING YARNS

GORE-TEX® Pro N80p-X fabric has a dense construction that minimizes the exposure of yarns to abrasive contact, reducing damage to filaments and maintaining surface integrity. Engineered for high impact and abrasion resistance, the N155p-X GORE-TEX® Pro fabric plies together multiple yarns in an Ottoman weave for maximum density, ruggedness and durability. These fabrics are more difficult to construct, but provide an exceptional durability and an ideal weight-to-strength ratio. Choosing the right material and the right construction is a cornerstone of the Arc'teryx commitment to craftsmanship.
