Innovative 3-layer design with 2 independent air chambers: have you ever waken up in the middle of the night because of a pinhole leak? Tired of back pain & discomfort due to rocks & bumps under your tent? Never sleep on a thin deflated mat again! Our sleeping mat ensures your good night's sleep even if one chamber is punctured - the other one keeps you from sleeping on a cold hard ground. Being a camping luxury, the mat provides additional insulation, maximum comfort & ergonomic support. Heavy duty, yet compact and lightweight: the ultralight sleeping mat weighs only 22 oz and packs as small as 4x11 in. Being the same size and weight as a small water bottle, it easily fits in your backpack and is effortless to carry around. The inflated size of 78х24х4 in works with all types of sleeping bags & is perfect for any outdoor activity like hiking, backpacking & traveling. Comes with a convenient bag & repair kit. Built for a lifetime of adventures: durable ripstop 40d nylon provides a unique balance between low weight & durability. 100% waterproof & tear resistant. Dual chamber design for superb insulation. Designed to last in severe conditions. Rain, snow, cold winter temperatures, uneven ground with lumps & holes will not compromise its excellent performance. Use this ultra comfortable 4'' thick mattress on a camping trip, in your hammock, on a floor, in your car's trunk or whenever life takes you! Easy to inflate and deflate: forget about your old sleeping pad that required a pump or long tiring minutes or inflating. The advanced inflation technology features 2 dual-action non-leak air valves for effortless & ultra quick inflation and deflation. 100% satisfaction guarantee: your satisfaction is our top priority. We are confident that our backpacking sleeping mat is warmer, more reliable & durable than others. If you are unhappy with your airpad for any reason, we will exchange it - no questions asked.
