High warmth paired with low weight and low cost? This pad delivers, thanks to weight-saving measures like the mummy shape and “bio-mapped” synthetic insulation (placed in key areas under the torso). That means less material but not less warmth, says a tester who used the Peak Elite on subfreezing nights.
The pad also gets a no-weight warmth boost (about 10 percent, says the company), from an aluminum coating*—particles infused in the fabric that reflect body heat. What we felt: 2.5 inches of luxurious cushion, and plenty of insulation for three-season use. The 33-denier ripstop nylon doesn’t need ultralight TLC, so the only real tradeoff is the shape: Are you comfortable without a full-size bed? $80; 14 oz.; 20”x 72”x 2.5”; pacoutdoor.com
