The Nemo Flyer Sleeping Mat is a rectangular, three-season sleeping pad with a 5cm thickness and 3.3 R-Value . Using a radical new hybrid design, the Flyer combines the thickness of an air pad with the plush durability of a foam pad with minimal weight consequences. It's the first self-inflated pad to use 3D-sculpting ! The Flyer features: 3.3 R-Value – tested to the new ASTM Standard (ASTM F3340-18) for thermal heat loss resistance 3D sculpted technology – removes 60% of the foam yet increases thickness by 290% when inflated Plush open-cell foam – offers a second level of security on the trail Horizontal coring – retains a higher R-value with less foam, so you dont have to sacrifice weight or packed size for warmth Micro-adjustable valve – zero-profile and multifunctional for fine tuning and fast inflation/deflation Ultralight 20D soft-touch fabric set – more pliable and comfortable than competitors Included repair kit – for emergency repairs out in the field. Enjoy a faster recovery after a hard day on the mountain with the Nemo Flyer Sleeping Mat.
