G'day Kelly,

I have gotten in touch with GSI Outdoors and they have advised it's not suitable to freeze these, this is what they have said. 'The water cube has walls that are thinner than others due to the manufacturing process. I think we would have leaks from the get-go if we froze that. Even if we left space. Just not meant for that application.'

G'day Richard,

The flow is mostly down to the lack of air intake, although like with a wine sack, etc squeezing does increase the flow!
You won't find the water cube as pliable as one of these sacks, but you should be able to put pressure on it for similar results.  I'd suggest it would be ideal to compress the cube along the existing fold lines, as if you are packing it up on itself, as opposed to just generally squashing it.

G'day John,

GSI does not specifically state that it's BPA free so we can only assume it's not.  Sorry mate!  

G'day Dudley,

I've just double checked our stock of the GSI Outdoors 10L Water Cubes on the shop floor and can confirm that they don't have a rope and hook for hanging the cube.
