New Atom SL Vest

Superlight and incredibly packable. Worn as a midlayer or standalone. The lightest Atom vest offers summerweight insulation for early morning runs and evening hikes. The Tyono™ 20 shell is light, breathable, and wind resistant, and the Coreloft™ insulation is compressible, dries fast and allows airflow. Lightweight stretch fleece side panels provide ventilation and zippered hand pockets stash small essentials. All in a package that weighs about as much – and packs as small as – an apple.

Size and Fit Tips: Fitted Fit – This trimmer fit is patterned to stay close to the body through the chest, waist, hip, and thigh. Its low profile eliminates bulk, moves with the body, and fits comfortably over our first layers.
