The Arcteryx Atom Vest adds core warmth without restricting your arms. Wear it over a base layer during activity or beneath a shell when you need more weather protection.
Coreloft Compact 60 insulation is lightweight, compressible and quick to regain loft. The Tyono 20 outer has a DWR finish to resist light moisture and wind, while a dope-dyed, air-permeable lining keeps the inside comfortable.
Stretch fleece side panels improve ventilation and movement but allow more heat to escape when you slow down. The fitted, hip-length cut layers neatly, and an insulated collar plus two zipped hand pockets complete the design.
