Improving on our original, best-selling Tensor line, Tensor™ Trail offers versatile 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. One layer of floating Thermal Mirror™ metallized film provides quiet insulation with an unprecedented weight-to-warmth ratio. Impressively quiet for uninterrupted sleep (and happy neighbors). Spaceframe™ baffles offer unparalleled stability and weight distribution, using low-stretch, die-cut trusses that eliminate springiness. 3.5 inches of stable, cushioned loft for incredibly comfortable nights. bluesign® approved premium nylon fabrics shave grams while offering superior puncture- and tear-resistance. Included Vortex™ pump sack provides easy and fast inflation, saves breath at elevation, and minimizes moisture entering the pad. Improved zero-profile, multifunctional, micro-adjustable Laylow™ valve offers customized inflation control, even in cold temperatures. Available in a wide range of sizes to easily pair with the rest of your sleep system.
