It works well. I prefer it over the neoair pump I have used, it's faster and inflates to a higher pressure. The only improvement would be to make it multifunctional such as a stuff sack or drybag.

I love my Tensor Extreme and Quasar 3D insulated pads, but . . . Pretty poor premise and design here. My Alpacka packraft inflation sack has a much wider opening and I can grab a larger amount of air with my hands vs. blowing into this contraption. If I can fill a packraft then I can fill an air mattress. Plus, who wants to be blowing air at 14,000 feet? I would suggest looking into packraft inflation sacks and produce a Nemo sack with a wide opening to grasp air by pulling the sides apart. No reason to reinvent the wheel . . .

Super easy to use and it fills my 4" Roamer Sleep Pad fast. I highly recommend it.

Nemo, your pads are awesome, I have two of them, really some of the best out there today. However this pump sack needs a redesign. Other pump sacks double as a watertight stuff sack for clothes or other items. This saves space and weight for ultralight hikers. Can you redesign this so the opening is larger similar to a stuff sack so you can fill it with clothes? Also the adapter to attach to pump up the Nemo pads should be closable. This would be awesome!

Hard to want to use this pump sack after using other brands. The opening on this is just too narrow to flick open with the wrists - instead you get a mostly uninflated bag of air...1/3 at best. Too bad because I love the Nemo Tensor sleeping pad.

The NEMO Vortex works really well as long as the adapter fits the diameter of the pad outlet valve. A caution, NEMO changed their diameter sometime in the past five years. I had to find a custom gasket to adapt the new pump sack to the old pad, which is still functioning perfectly in all other ways. I think the product description should have pointed this out.

This pump sack makes inflating your Nemo sleeping pad a breeze. I used to dread the process but with the Vortex it's super easy. It's nice and packable, too.

I got one of these with a Tensor sleeping pad. It's nice to have and makes blowing up the pad easier, but I wish it could serve dual use as a stuff sack/dry bag like other manufacturers have. The opening is really too narrow to be useful for this purpose. It's fine for car camping but harder to justify if you are backpacking and trying to shave ounces from your kit.

Just used this for two nights with two Nemo Astros. Worked well. Took three vortex bags plus a couple breaths to fill up a long wide Astro. Almost have to have it. Wouldn’t want to blow one up on breath power alone.

This pump sack works perfectly with the Nemo sleeping mats. It folds up nicely and yet also inflates the mat with only a few air loads. Great product. It would be nice if the valve was compatible with other mats, such as the Exped.

No regrets with this purchase. Setting up is so much easier when the inflation of the sleeping mat is a non-event! My 3 1/2 inch thick air pad is ready in no time.

I've always hated inflating my sleeping pad and seeing the condensation collecting...gross! I'm so glad I got this pump sack. It makes inflating easier - without the moisture collecting. It also doubles as a dry sack.

Ultralight, speeds up air mattress inflation without introducing moister into air mattress. Doesn’t take up any additional space in backpack.

Bought this for a NEMO Cosmo™ 3D Sleeping Pad Long Wide because I use it in a small tent and the foot pump took too long when trying to inflate when you're kneeling. The Vortex worked great, about 6 full sacks and the inflation was complete. In addition it's pretty rugged and takes up very little space in my pack. .

This came with my sleeping pad, winter expeditions require as little moisture as possible entering your sleeping pad (the purpose of these pump sacks is that they pump dry air into the bag and prevent the build up of condensation) this bag defeats that purpose by requiring you to inhale into it. Recommend getting a pad with the interested foot pump for winter expeditions and to avoid condensation.
