Nemo has confirmed that they have discontinued the Disco Pad Pump, though you may still be able to find it on sale at major retailers. If you're in search of a pad pump, check out the Therm-a-Rest NeoAir Pump Sack, a Top Pick award winner.
The Nemo Disco Pad Pump is a lightweight portable foot pump for your sleeping pad. The Disco inflates with one breath and then can be used as a foot pump. This is the lightest pump we know of and could be a good option for winter use, when water vapor from your lungs condenses inside a sleeping pad.
Although the Disco Pad Pump is lightweight and innovative, we prefer the Therm-a-Rest NeoAir Pump Sack because it's more versatile. The Pump Sack can be used as a stuff sack, pack liner, or chair.
