I have the Big Zip 3 liter and I love it. BPA-free and easy opening.
I used to have the 2L but recently got a 3L and I'm glad I did.
I like how there is a divider in the bag so the water fills evenly.
I also like how it is BPA free.
I prefer the Big Zip over the Hoser because I can open the bag with ease to put more water in and to pour out.
