Arc'teryx Atom SL Hoody Jacket Mens

ac3atsh04blk20
Warm weather is never a constant, even in summer. Fog rolls in, a sudden thunderstorm blocks the sun, and changes in elevation and levels of exposure can cause temperatures to suddenly shift. But summer conditions seldom require bulky insulation. The Atom SL Hoody is specifically created to hit the zone where insulation is required, but in a measured amount that suits milder conditions. Providing warmth comparable to a lightweight fleece for significantly fewer grams, the Atom SL is an efficient midlayer in cool conditions and a great standalone during rest breaks, early morning starts, and while enjoying the view from a freshly bagged peak.

The Atom SL is designed to handle subtle climate shifts. Balancing air permeability with wind resistance, the shell material allows airflow during active periods, but helps cut the chill during static moments. 40g/m² Coreloft™ Compact insulation is highly compressible, insulates if wet, and delivers its superior performance for very little weight. All the Atom SL’s fabrics are selected to manage moisture and provide comfort while on the move. Sleeves are lined with a comfortable mesh, and lightweight fleece side panels help provide thermal performance and ventilation. Articulated sleeves and gusseted underarms extend freedom of movement.
