Compact but efficient, the NeoAir Micro Pump can rapidly inflate your sleeping pad before conveniently fitting inside your backpack. Weighing just 2.3 oz (65 g), this pump operates on two AAA batteries and can inflate your WingLock or TwinLock pad within minutes. Additionally, if you have a NeoAir pad equipped with a WingLock valve, this convenient pump can also deflate your mattress before packing it up and embarking on your next adventure.
