Description
Atom SL Jacket Women’s is the lightest, most packable insulated jacket designed for alpine and hiking, built for high-output efforts in cold, wet conditions.
- Product Type: Women’s packable insulated jacket.
- Material: Synthetic Fill.
- Weight: 205g.
- Breathable and wind resistant for active movement in variable weather.
- Stretch insulation in the body with uninsulated sleeves to focus warmth on the core and maximise packability.
- Wear as a standalone layer for cold, wet trail runs or under a waterproof shell for added warmth and mobility.
For alpine and hiking, layer it with a women’s shell jacket and pair with women’s softshell pants.
Lighter than the original and with the same features as the hoody by the same name (minus the hood, of course), the Atom SL Jacket is one of the most useful (and packable) pieces you can own. Wear it as a standalone layer when trail runs take you through cold, wet weather or layer it with a waterproof shell when mountain pursuits demand additional warmth and mobility. Breathable and weather-resistant, it has stretch insulation in the body but not the sleeves — maximizing packability while still delivering focused warmth to your core.
