Improving on NEMO’s best-selling original Tensor line, the 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 uses low-stretch fabric trusses to create stable support, and offers 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, the 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. Two layers of floating Thermal Mirror™ metallized film provide 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 the amount of moisture entering the pad Improved zero-profile, multifunctional, microadjustable Laylow™ valve offers customized inflation control, even in cold temperatures Type Inflatable, Insulated Capacity 1-Person Shape Rectangular Length Regular Width Regular Thickness 3.5 in Activity Backcountry/Thru-Hiking Seasons 3-Season R-Value 5.4 Inflation Valve Laylow™ Valve Structure Spaceframe™ Baffles Pump Sack Vortex™ Insulation Thermal Mirror™ | Aluminized Film | 2-Layer Construction Nylon | bluesign®-Approved Dimensions 72 x 20 x 3.4 in / 6 ft x 20 in x 3.4 in 183 x 51 x 9 cm Packed Dimensions 10 x 4 x 4 in 25 x 10 x 10 cm Weight Total 18 oz 510g Minimum 16 oz 454g
