After more than two years and 21 countries over 50,000 miles on the road, it takes just a lick of sense to stay selective about what we carry. And without question, it has to fulfil: less is more and size does matter. Namely space and weight will always be at a premium when living out of two motorcycle panniers and a roll bag.
An absolute prized possession in all of my camping equipment. Why? Because I'm too lazy to blow my mattress up day in, day out when I could be undertaking something f...ar more constructive like getting the tea on. On a more serious note, puffing breaths into my pad and my partner's larger one can sometimes leave me dizzy and lightheaded, especially at altitude or at the end of hot days.
Based on Bernoulli's Principle of fluid dynamics goes a long way towards explaining why the sleeping mattress inflates in no time at all. Mind-blowingly quicker than sole use of your breath alone. Allow me to expound on the physics: plugging the dry sack at the bottom around the valve on the mattress, and blowing into the top of the dry sack about six inches away from the opening, I seal the bag as I would any regular dry bag. Gently squeezing the bag down, a rush of low-pressure, fast-moving air charges into the mattress, causing the static high-pressure air outside the pad to rush in and equalize the pressure. It's incredibly fast, much cleaner and requires hardly an ounce of effort than with traditional valves. There's nothing not to love about this brilliant item.
It's always been a problem, moist air when inflating a Neoair, nearly passing out when blowing it up. The pump sack sorts this out. Even when inflating on a rain soaked campsite, confined in my one man tent. I managed to keep everything dry and inflate the Neoair. Quicker than the mini pump and no batteries needed.
Therm-A-Rest NeoAir Pump Sack The Therm-A-Rest NeoAir Pump Sack will inflate your NeoAir mattress quickly and easily, but its function doesn't stop there. The 40 liter sack doubles as a stuff sack, or pack liner, and it can also be used to convert a NeoAir mattress into a Jembe style camp seat. Just insert a rolled NeoAir mattress, and inflate for lightweight campsite seating. Protect your NeoAir pad, and increase its versatility, because this bag actually helps to inflate your NeoAir mattress. It is made of waterproof 70 denier ripstop nylon. Just like the storage sack, the top of the Pump Sack has a draw-cord running around the edge, that secures it with a spring-loaded cord-lock. At the bottom is a black-edged grab handle, useful for carrying the Pump Sack, if it were to be full other items. The plug is a disk of flexible clear urethane-type material, that is chemically welded to the nylon of the Pump Sack. The Therm-A-Rest NeoAir Pump Sack is useful for many other inflatable things, making it extremely versatile.

The valve from your mattress fits snuggly into a Vinyl hole under the handle strap on the closed end of the sack.
You then trap air in the sack by closing the large open end and then push the air into the mattress.
It worked great when I used it, allowing me to fill my Neo Air XLite mattress quickly with just three sacks full of air, and then just a breath or two to fine tune.

It comes with a coupler to connect it to the NeoAir valve.

There is a piece of clear vinyl about 1in square sewn into the center of the closed end of the bag. This piece has a hole in the center, through which the valve on the air mattress is inserted and forms a seal around the valve. Thus the air forced out of the pump bag goes into the air mattress. So, no, the pump bag doesn't have a valve but is designed to form a seal without a valve.
