Therm-a-Rest NeoAir Camper SV Sleeping Mat - Large



Item #: 332051175

When Therm-a-Rest took their thick, ultra-supportive NeoAir® Camper mattress and added their new SpeedValve™ design, they created the 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, reflectiveThermaCapture™ technology and WaveCore™ 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.
