Set it and forget it.
Another addition to its super light category, the Arc'teryx Men's Atom SL Vest delivers soft, breathable warmth where you need it most. With just the lightest touch of synthetic insulation, air-permeable fabric, and ventilated side panels, the Atom SL is the ideal layer when you're moving through cold, blustery weather that doesn't necessarily demand full waterproof protection. The Coreloft insulation is lightweight, so you won't overheat during an arduous multi-pitch or spring tour, and it holds its warmth even when wet. The fleece stretch side panels provide ventilation when you're constantly on the move, and the adjustable hem can be cinched down to seal out wind.
