“It’s Hyatt-level comfort for only a pound,” says one tester, who calls the ounce-shaving mummy shape and 3.5 inches of cushion “the ideal balance of efficiency and comfort.” Instead of using vertical or horizontal tubes, the Q-Core welds both types together in a quilt-like pattern that delivers outstanding stability.
“There’s no raft-like rebound when I roll over,” says a tester. A thin layer of synthetic insulation boosts the R-value to 4.5. In Colorado’s Park Range, our tester slept warm through a 20°F night—in a 30°F bag. Downside: The superlight nylon shell material requires TLC. $160; 1 lb.; 70” x 20” x 3.5”; bigagnes.com
