A pump that doubles as a dry-sack, the Sea To Summit Airstream Pumpsack will inflate a Sea To Summit Sleeping Mat in just two to three cycles.
No more dizzy heads, and no extra weight, once you've unpacked your gear from the dry-sack, open the base and attach it to your sleeping mat and with minimal breath and condensation your mat is inflated and ready for rest.
I have purchased both the Sea to Summit pumps to inflate my Large Comfort Plus Insulated Sea to Summit mat. I found the Jet Stream pump to be a great "little pump" its spring wire frame makes for easy pumping only issue is that it is quite small and takes a lot of pumping to inflate the whole mat. Air Stream Dry Sack is a fantastic large "pump" unlike the Jet Stream this doesn't automatically fill but after a short breath to expand the bag full of air you just roll the large volume of Air into your mat. Overall I probably prefer the Air Stream Dry Sack as it fills my mat so much quicker and easier with only 4 "pumps".
In regards to purchasing off Snowys I have found them to be the best outdoor seller to date. Excellent pricing! Great staff with quick and helpful responses on the Online Chat and emails! The items get shipped straight to your door!
Takes a little getting used too, however once you get the hang of it it only takes a couple of bags to fill the mattress. It's amazing and when you're not using it you can carry things in it. Sea to Summit excellent gear.
Or would I be better off with a compression bag for the sleeping bag and use this for something else?
For the sake of durability and easier packing, I would recommend getting a compression sack and using the Sea to Summit Air Stream Dry Sack for something else. The Air Stream Dry Sack is quite thin and compact and could just be rolled up with the sleeping bag if need be.
Will it fit the large insulated ultralight?
Just the one size in the Sea to Summit Air Stream Dry sack. Your Sea to Summit Ultralight Insulated mat will fit no worries.
Are there any adapters that could be used to increase its compatibility with mats made by other manufacturers?
Unfortunately the Sea to Summit Air Stream Dry Sack is currently only compatible with the range of Sea to Summit mats and there is no adaptor available.
We are not aware of any adapters for this pump sorry Darrell.
Is this compatible with Exped SYNMAT valve?
The Sea to Summit Air Stream Dry Sack is not made to be compatible with Exped Mats, so it's not going to fit with the Synmat unfortunately.
Will this work with the thermarest mat - neoair?
Unfortunately the valves are different sizes so this pump won't work with your Thermarest mat, sorry!
Hello Snowy, What is the liter capacity of the S2S Air Stream Dry Sack when not used as a pump and just how is it fill with air when it is used as a pump?
The Sea to Summit Air Stream Dry Sack has a 20-litre capacity, and to fill it with air you just blow into it once and the sack will be inflated.
To get an idea of how many compressions are necessary to inflate a mat, a Sea to Summit mat will take two to three compressions with the Air Stream Dry Sack.
