“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

The Dualis ST offers patent-pending Dualis Technology that combines the performance of an air tube pad on the top with a self-inflating mattress on the bottom for the comfort of a home mattress in a compact size for the outdoors. Each sleep pad has thermoplastic polyurethane (TPU) laminated soft-touch anti-slip fabric on the air tube chamber and durable anti-slip 150D polyester oxford ripstop with TPU lamination as the ground fabric, offering durability and slip-resistance.
