The Thermarest NeoAir Camper SV Sleeping Pad. Deluxe basecamp mattress with fast & easy inflation/deflation. Take the ultra-supportive NeoAir(R) Camper mattress and add the new SpeedValve(TM) design; its fastest way to feel at home in the outdoors. Using simple physics, the special valve allows you to inflate your insulated mattress up to three times faster than traditional valves, with a fraction of the effort. Once inflated, reflective ThermaCapture(TM) technology and WaveCore(TM) construction combine hundreds of internal cells and efficient, radiant heat capture to deliver reliable, compact three-season comfort. When it's time to break camp, the patent-pending, auto-reversing valve deflates the mattress almost instantly. Stuff sack and repair kit included.
