Lighter than the original, but with the same features as the hoody, which has the same name (just without the hood), the Arc'teryx Atom SL jacket is one of the most practical (and packable) outdoor pieces you can own. It's breathable, weather resistant and has stretch insulation on the upper body but not in the sleeves. This maximizes packability and warms the upper body.

- Moisture-resistant outer fabric
- Body-hugging fit with anatomically pre-shaped cut for mobility and comfort
- Mesh-lined sleeves without insulation provide lightweight protection and regulate temperature
- Adjustable drawcord in hem keeps drafts out
- Two hand pockets with concealed zippers
