Great Product, Fast Shipping

Gave this product 4 stars plus 1 extra because of fast shipping. Ordered this plus the Sea to Summit pillow on a Monday morning and had it arrive in Melbourne at 9am on Tuesday. Really amazing service Snowys, you guys rock!

The product itself makes inflating my S2S pillow a breeze. One bag full and the pillow is completely inflated. Used it to pump up my S2S insulated sleeping mat, but found I always had to top it up with one or two extra breaths. I would always get to a point where no more air could be pushed out of the pump, however once pump is removed, find it still has room to breathe into.

Works great but just requires one manual puff at the end.

Awesome all rounder

It's fantastic! Big enough to hold our sleeping gear, doubles as a dry sack and then we can inflate it all when we arrive! Worth it!

Sea to Summit Pumps

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.

Comfort Plus Insulated Mat fit in?1 answer

Will the Sea to Summit Comfort Plus Insulated Sleeping Mat fit inside this?

- SA(7 months ago)

The Air Stream Pump Sacks are pretty large sacks Kate, you'll easily fit any of the Sea To Summit hiking mats into this, along with a bit of other gear.

They are made of lighter weight material than the regular stuff sacks, so I'd keep the contents of it to soft items such as your mat and some clothing.

Would the BW Micron 220 sleeping bag fit in?1 answer

Or would I be better off with a compression bag for the sleeping bag and use this for something else?

- Bentleigh(8 months ago)

G'day Jan,

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.

Are there different sizes ?1 answer

Will it fit the large insulated ultralight?

- Melbourne(8 months ago)

G'day Ian,

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? 2 answers

Are there any adapters that could be used to increase its compatibility with mats made by other manufacturers?

- Belmont(8 months ago)

G'day Darrell,

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. 

- Snowys(8 months ago)

G'day Darrell,

We are not aware of any adapters for this pump sorry Darrell.

Is this compatible with Exped SYNMAT valve?1 answer

Is this compatible with Exped SYNMAT valve?

- Braitling(12 months ago)

G'day Tim, 

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 air stream dry sack work with the thermarest mat - neoair?1 answer

Hi Graham, 

Unfortunately the valves are different sizes so this pump won't work with your Thermarest mat, sorry!

SeatoSumit Air Stream Dry Sack1 answer

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?

- Albury NSW(1 year ago)

G'day Michael, 

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.
