Improving on the best-selling original Tensor line, Tensor™ Trail offers greater warmth for three-season adventures where weight is the top priority. Designed to take you from spring to fall, it keeps nights restful and packs up light. The pad’s interior features Nemo’s proprietary Spaceframe™ baffle design, which utilizes low-stretch fabric trusses to create stable support and offer just the right amount of give all while avoiding any wobbly waterbed feeling. Inside each baffle is a suspended layer of ultra-thin, metallized Thermal Mirror™ film, which efficiently reflects body heat and contributes to the pad’s overall 2.8 R-value. The layer’s clever floating construction eliminates the crinkling, crunchy sound that many insulated air pads are known for, earning Tensor a reputation for peace and quiet under the stars. Armed with premium, durable 20D (top) and 40D (bottom) nylon, Tensor Trail is better protected against punctures and tears, and like all Nemo sleeping pads, it includes a Vortex™ pump sack. Vortex™ effortlessly mates with the pad’s zero-profile, microadjustable Laylow™ valve for easy inflation in just minutes.
