The Tensor ultralight sleeping pad is the minimalist's best friend, offering 3" of back-saving, cushioned sleep with a paltry weight and pack size. This is the lightest air mattress in the NEMO family, using premium 20-denier fabrics to shave grams, and achieving a revolutionarily lightweight sleeping pad that doesn't sacrifice comfort and packs down as small as your water bottle.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.The Thermal Mirror(TM) metalized film layer provides insulation, and - because it is suspended in the middle of the pad - doesn't make a crunching sound like some pads. Insulated versions of Tensor add a layer of Primaloft for even more warmth when the ground is cold.20R Minimum Weight: 15 oz.20L Minimum Weight: 16 oz.25R Minimum Weight: 1 lb. 3 0z.25L Minimum Weight: 1 lb. 5 oz.20R Packed Size: 7.9 x 3.5 inches20L Packed Size: 7.9 x 3.5 inches25R Packed Size: 9.5 x 3.7 inches25L Packed Size: 9.5 x 3.7 inches20R dimensions: 72" Long x 20" Wide x 3" Thick20L dimensions: 76" Long x 20" Wide x 3" Thick25R dimensions: 72" Long x 25" Wide x 3" Thick25L dimensions: 76" Long x 25" Wide x 3" ThickSpecs:The large Pillow Baffle at the head end of the pad ensures that your pillow doesn't slide off in the middle of the nightAn integrated foot pump makes setup fast and gives your lungs a restA large dump valve quickly expels air so that you can takedown in a flashDark Fision Color
