Packing to the size of a 32-ounce water bottle and delivering ground insulation, the NEMO Tensor Trail Sleeping Pad is a comfort item and ultralight option in one. The floating Thermal Mirror reflects our body heat back to us without making a sound when we shift, and the zero-profile valve lets us get the feel just right for ultimate comfort in the backcountry. From camp to camp, this pad rolls up and stuffs away compactly, adding just a pound to our pack.
