Backcountry Staple
If you don’t already have a jacket like the Atom LT Hoody in your quiver, it’s time to add one. What’s so great about it? Because it’s lightly insulated with a highly compressible synthetic fill, it’s impressively warm for such a light and packable jacket. Plus its stretchy and uninsulated panels of fleece under the arms make for a less bulky fit and up the comfort factor. If a lightweight down coat is an essential piece of insurance for winter trips into the backcountry, this is the summertime equivalent. Bonus: Come winter, its trim cut makes it the perfect midlayer for resort skiing. Also available without a hood for $179. 13 oz;
