Mountain Equipment Aerotherm Men's Vest

A lightweight, wind-resistant, and quick-drying vest offering added insulation for mountain hikes and trail runs.

Crafted from an ultra-light double weave soft shell fabric and lined with a moisture-managing micro-grid, this adaptable windproof vest supports temperature and sweat regulation on uphill climbs. It then provides essential warmth when pausing on breezy summits and along exposed ridgelines. With rapid drying after exertion, this is a go-to layer that can remain on during shifting mountain conditions—be it while running, hiking, or scrambling.

The semi-elasticated armholes and hem ensure a secure, comfortable fit that helps fend off draughts, while zipped hand pockets and a chest pocket offer space for essentials. The vest stows easily into one of its own hand pockets and features twin carry loops for clipping to a harness or pack—perfect for fast-moving days in the hills.
