Mugs are awkward to stow (we don’t like to clip them outside our packs where they pick up dirt or snag on branches), with the exception of this collapsible version. The Cool Grip X-Mug packs down into a 4.5-inch-wide, .8-inch-tall disc that slips easily into a side pocket or any crevice of free pack space. “It’s actually the most compact piece of gear in my mess kit,” one tester said after hiking a section of the Appalachian Trail in New Hampshire. A ribbed exterior not only provides grip for this handle-less cup, but also keeps your hands from burning thanks to the design’s ability to absorb more heat than a thinner, smooth mug wall. Backcountry chefs rejoice: The 16-ounce X-Mug’s interior also has both metric and imperial tick marks for measuring volume.
