La Sportiva Men's Alya Vest

Core Warmth Meets Breathable Trail Mobility

Best For: Cold-weather trail running, fast-and-light mountaineering, and high-output shoulder-season hikes through Maritime wind and drizzle.

Lock in core heat against sharp Atlantic gales with dual-zone PrimaLoft ThermoPlume and PrimaLoft Silver synthetic insulation across the chest. The ultra-lightweight Pertex Quantum outer shell acts as an impenetrable shield against biting winds while maintaining a packable, featherlight profile.

Dump excess body heat naturally during steep ascents thanks to the breathable stretch paneling along the back and sides. This high-flex design moves fluidly with your stride, preventing sweaty buildup on intense ridge runs or fastpacking trips through coastal barrens.

Transition seamlessly across seasons with thoughtful trail-ready features like a chest snap button for quick, secure venting without unzipping completely. Stash your morning coffee card or trail gels in the dual hand pockets, making this sleek insulated layer an essential piece for both dawn-patrol runs and post-workout coffee rituals.
