G'day Troy,

They are quite durable, so there's no need to really worry about leaking. Personally, I'd opt for 2 x 6L purely so that you can even out your carrying weight a little more easily.

G'day Troy,

These Water ST Water Storage bags are best paired with a reusable wide mouth water bottle. They have a carry handle that can be used to aid in pouring, but you might find you lose some water if pouring into a smaller disposable bottle-style lid. It might be worth considering the Watercell X as they have a different cap that features a smaller inner cap that would make pouring into a narrow neck bottle a little easier.

G'day Andrew,

The ST model is the streamline version and is made from a lighter weight material. The X model is made from a more robust 400D nylon and includes the option to hang it and use it as a shower too.
