Improving on our 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 seasons 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, micro adjustable Laylow valve for easy inflation in just minutes.
