Arc'teryx Atom Vest Men's delivers the familiar warmth of the Atom series in a more mobile and compact version. The vest is developed for cool days when you need an extra insulating layer without sacrificing freedom of movement. It works equally well on its own during long hikes and climbing sessions as it does under a shell jacket on wet or windy winter days.

The synthetic Coreloft insulation retains warmth even in light moisture, making it a reliable choice for high-intensity activities throughout the year. The materials are lightweight, breathable and partly recycled, with Fortius Air 20 fabric on the inside providing comfort and effective ventilation. The sides are made from stretchy Octa fleece, which enhances mobility and helps the body regulate temperature during activity.

An FC0 DWR treatment ensures that light precipitation beads off without the use of added PFAS substances. The fit is ergonomically designed for natural freedom of movement, and the hem can be adjusted to keep out draughts. Two discreet hand pockets with concealed zips provide secure storage for small items. The vest is made with materials that meet bluesign requirements and contain recycled content, as well as an odour-reducing Polygiene treatment.
