Why We Like the Vortex Pump Sack
Gone are the days of nearly fainting while inflating a sleeping pad at high altitudes. Nemo's Vortex Pump Sack fills with light breathing, and you can breathe about a foot away from the sack to inflate it with as little condensation as possible for colder treks.

Needs redesign to be like Packraft sack
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 . . .

Great way to avoid the huffing and puffing
Super easy to use and it fills my 4" Roamer Sleep Pad fast. I highly recommend it.

Needs modifications to double as a Stuff Sack.
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!

opening too narrow- only 1/3 useful
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.

Does its job and nothing else
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.

The right pump sack for the job
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.

perfect companion to my Tensor sleeping pad
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.

Still inflates your sleeping pad with moist air
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.

Smaller opening, but works fine
It works as advertised - the pump sack is included in each sleeping pad order, which I was unaware of, so this was essentially an extra and unnecessary purchase.

Better than others, but not the best
I have used other manufacturers version and I think this is the best one if but for one issue... Please build this function into your sleeping mat stuff sack. There should be a reason that the stuff sack cannot also act as an inflation devi e so I have one less item to try to keep track of.

Will these attach to the roamer? and if so will it fill without removing the one way valve?

Will this work with the older cosmo insulated sleeping pads? (The ones with the foot pump)

Can you explain more about how it works with old Tensor models that have the valve that stick up. How to you seal it around a older valve?

In March 2019, I bought the Nemo 20R Tensor insulated sleeping mat (label says manufactured in 2017). Is the Vortex pump sack compatible with this model? Pity you didn't have one then...

Is this comparable with the older Tensor w/o the one way valve?

The whole purpose of having a pump sack is to reduce moisture entering the sleeping pad from ones breathe. how does this pump sack help that situation if one needs to exhale into it? I had severe issues in the past with the insulated Astro freezing on me.
