Improving on the best-selling original Tensor line, Tensor™ 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 season and keeps its reputation for low-decibel dozing. 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 are two suspended layers of ultra-thin, metallized Thermal Mirror™ 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™ pump sack. Vortex™ effortlessly mates with the pad’s zero-profile, microadjustable Laylow™ valve for easy inflation in just minutes.
