You might think low-profile and low-center-of-gravity designs are just for kayaks and other highly engineered items. Get this--GSI Outdoors created the Ultralight Nesting Bowl and Mug with those two design features, so you're less likely to spill hot beverages and food when your hands are shaking from the cold. Or when you're too sleepy to be super careful with a hot cup of coffee in the very early morning before your ascent. A foam-insulated sleeve helps keep your drinks hot, and the Ultralight Nesting Bowl and Mug's Sip-it top keeps your beverages hot.
