Therm-a-Rest NeoLoft Sleeping Pad

It may not look like it, but make no mistake, the NeoLoft is a true backpacking sleeping pad. From the inside out, every element of the NeoLoft comes together to deliver sublime comfort while remaining incredibly light and packable. 3D construction elevates the pad to 4.6 inches (11.7 cm) thick, making the NeoLoft a side sleeper's dream. Vertical sidewalls attach the top and bottom fabric and eliminate the tapering edges of non-3D pads. This increases the sleep surface by 20% and delivers excellent stability—you'll never feel like you're falling off while you adjust to get comfortable. On the outside, the NeoLoft's surface is made of a plush stretch knit fabric (the NeoLoft is the first ever air pad to be made with stretch knit). Stretch knit is a base layer-like fabric with multi-directional elasticity and is FAR softer to the touch than the nylons typically used to make backpacking pads. Its stretch properties improve the NeoLoft's contouring support and help to minimize pressure points by locally conforming to the shape of your body. On the inside is the ContourCore Matrix™—the epicenter of the NeoLoft's backcountry-ready specs. It efficiently insulates by minimizing convective heat loss with two stacked rows of triangular chambers, while ThermaCapture™ reflects body heat back at you, delivering a year-round R-value rating of 4.7. Along the sides we built in large chambers that rise to form side rails when the pad is inflated. These give your body a tactile sense of the pad's edge and cradle you towards its center to prevent roll-offs. We fitted the NeoLoft with our high-volume-pad TwinLock™ Valve System. The two-valve system rapidly inflates the NeoLoft with a dedicated 'In' valve featuring one-way air flow, and quickly dumps air with a dedicated 'Out' valve. Paired with a high-volume, seam-sealed pump sack, the NeoLoft blows up and packs out quickly and efficiently.
