Improving on Nemo&';s best-selling original Tensor line, Tensor(TM) All-Season offers greater warmth for four-season use without adding any weight. Designed to be a go-to pad all year long, it straddles all seasons and keeps its reputation for low-decibel dozing. The pad&&';;s interior features NEMO&&';;s proprietary Spaceframe(TM) 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 are two suspended layers of ultra-thin, metallized Thermal Mirror(TM) film, which efficiently reflect body heat and contribute to the pad&&';;s overall 5.4 R-value. The layers&&';; clever floating construction eliminates the crinkling, crunchy sound that many insulated air pads are known for, earning Tensor a reputation for peace and quiet on the trail. Armed with premium, durable 20D (top) and 40D (bottom) nylon, Tensor All-Season is better protected against punctures and tears, and - like all NEMO sleeping pads - it includes a Vortex(TM) pump sack. Vortex effortlessly mates with the pad&&';;s zero-profile, microadjustable Laylow(TM) valve for easy inflation in just minutes. Features Two layers of floating Thermal Mirror(TM) metallized film provide quiet insulation with an unprecedented weight-to-warmth ratio. Impressively quiet for uninterrupted sleep (and happy neighbors). Spaceframe(TM) 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. bluesignA(R) approved premium nylon fabrics shave grams while offering superior puncture- and tear-resistance. Included Vortex(TM) pump sack provides easy and fast inflation, saves breath at elevation, and minimizes moisture entering the pad. Improved zero-profile, multifunctional, microadjustable Laylow(TM) 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. Protected by the NEMO Lifetime Warranty.
