Why spend more money on a sleeping bag? Logical question, of course. But for any backpacker eager to shave a pound or more and significant gear volume from his or her backpack, an ultralight down bag offers one of the best ways of realizing that objective—as well as delivering maximum warmth per ounce. And one of the lightest and most compact bags in this category, Therm-a-Rest’s Hyperion 32F/0C, measured up in every way on a six-day backpacking trip in the Grand Canyon in May; a six-day float trip down Idaho’s Middle Fork of the Salmon River in July; a three-day hike on the Teton Crest Trail in August; a five-day, late-summer hike in the Wind River Range; trekking hut-to-hut on New Zealand’s Routeburn and Milford tracks in late spring; and on chilly, rainy spring nights that pushed the bag’s limits camping in May in Idaho’s City of Rocks National Reserve.
