Arc'teryx Atom SL Womens Jacket 2026 Color:Black True to its legendary rootsLightest, most packable Atom Jacket for big efforts in cold, wet conditions. 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.
