Look at specs when shopping for a high-quality, ultralight, three-season sleeping bag and you might quickly trim your short list to about five models, all at basically similar weights and price points. But having slept in most of those top bags—and after sleeping in Mountain Hardwear’s Phantom 30 on cool nights on backpacking trips from a section of the Arizona Trail in the first days of April and camping at Idaho’s City of Rocks in June to the Canadian Rockies and Wind River Range in August—I place the Phantom 30 among the two or (maybe) three very best ultralight mummy bags for its strategic balance between low weight and excellent warmth.
