Ultralight Softshell Performance for Technical Mobility

The Arc'teryx Men’s Gamma SL Short 9" (previously known as the Gamma Lightweight Short) is the lightest softshell short in the Gamma collection, specifically engineered for fast-paced hiking, technical climbing, and long backcountry miles. Constructed from recycled Fortius™ 1.0 double-weave fabric, these shorts strike an elite balance between high breathability and rugged wind resistance. The performance-driven stretch material allows the garment to dump heat efficiently during steep climbs while offering durable protection against abrasive rock, grit, and trail obstacles.

Designed to provide a streamlined, uninhibited stride, the Gamma SL features articulated patterning and a gusseted crotch that delivers a full range of motion. The refined design features an updated, low-profile integrated webbing belt system with a sturdy metal buckle that sits completely flat and comfortable under a backpack hipbelt or climbing harness. Coated with a sustainable, PFAS-free FC0 DWR finish to shed unexpected rain showers, these technical shorts are finished with secure zippered hand pockets and a harness-friendly thigh pocket to keep small trail essentials safely stowed.
