Built for ounce-counting backpackers, the Klymit Insulated Static V Lite inflatable sleeping pad delivers packable year-round performance at a weight of just 20 ounces! The pad's unique, pocketed V-chamber design increases warmth and provides excellent support and comfort. Klymit's signature strategically oriented V-chambers offer a comfortable sleeping base but also help to trap air and keep you warmer than traditional inflatable pads. Horizontally-baffled side rails help to keep you situated on your pad at night. Because of its weight-saving design, the pad inflates in just 10-15 breaths and the integrated valve makes inflation and deflation easy while ensuring a secure closure. Klymalite synthetic insulation in the air chambers bolsters warmth and grants the pad a year-round worthy 4.4 R-Value. The Klymit Insulated Static V Lite sleeping pad has 72' x 23' x 2.5' dimensions but packs down to a backpacking-friendly 8' x 3' in its included stuff sack. It weighs just 20 ounces.
