The Nemo Tensor Insulated Mummy Ultralight Sleeping Pad - The Nemo Tensor Insulated Mummy Ultralight Sleeping Pad offers 3 inches of back-saving, cushioned sleep with a paltry weight and pack size. The lightest air mattress in the Nemo family, they've achieved a revolutionary lightweight sleeping pad that won't sacrifice comfort. Great for the minimalist. Nemo Spaceframe baffles are an ingenious invention that allow for a quieter, more stable sleeping experience. This technology uses low-stretch die-cut trusses to eliminate springiness found in competitor pads, and is better for rolling side-to-side and for keeping your elbows from poking through to the ground when propped up reading.
