Warmth In cold weather, your bag is only as good as your pad. The Big Agnes Q-Core SLX inflatable mat’s recipe for warmth: short-staple synthetic insulation plus heat reflective material, which kept our editor warm while snow camping on Canada’s Spearhead Traverse. The pad is rated to 15°F, and has a one-way valve for inflation and a separate hole for rapid deflation.
Comfort This 4.25-inch-thick pad has I-beams—picture dozens of superlight nylon ribbons connecting the top and bottom—that create a quilt-like structure that feels flat and stable, even when errant footprints pocked our snow platform and made for an uneven sleeping surface. 72” x 20” x 4.25”
