The NeoAir All Season SV mats are exceptionally compact, light and rugged four-season mattress with ultra-fast inflation/deflation. This cult favourite, four season, go-anywhere air mattress just got better. Now sporting the game-changing SpeedValve™, the rugged All Season inflates up to three times faster and deflates instantly. Multiple layers of ThermaCapture™ technology make it one of Thermarest's warmest and most versatile NeoAir mattresses. Stuff sack and repair kit included.
The All Season SV is inflated quickly with the innovative Speed Valve which makes inflating and deflating the mattress much easier as it sucks in air from the outside as you blow into it, so not only does the mat inflate quicker, you use less breath. The speed valve also makes deflating the mat almost instant, so packing it away is quick and easy.
