I purchase the gallon bottle and got the free bag because it was cute and who does like free stuff...lol...It took me awhile to finally add it to cart and check out because it's a pretty high priced item for a bottle, but since you get a bag that, in pictures and videos, shows it can hold your phone and keys it would be worth it.
When I received my order I was in love with the bag and the color of the bottle. The unfortunate thing is that the bottle came with a green smudge on the bottom that I had to gently srub off which left a very faint discoloration, but I figured since I was carrying it in the bag it wouldn't matter. When I did try to put the bottle in, I did have to stretch out the top to get it in, it was a snug fit. I loved the look, but noticed that since the gallon bottle fits super snuggly into the bag there was no way for me to fit my phone into the pocket because the bottle/bag is curved and the phone is straight. Also when I tried to put my keys and my card wallet into the pocket, again was a snug fit, it actually curved my card wallet and my keys could barely fit.
So I went from excited, thinking I could just carry everything in one bag to now slightly disappointed that I have this big water bottle in a cute bag that can carry my keys and maybe my ID and a debit card that could potentially get misshappened. I also need to plan to make sure I either wear something that has pockets to carry my phone or a bum bag or just ditch the whole thing altogether.
Just a design suggestion may be design a gusseted pocket or a separate pocket that has a bit more width and doesn't hug the bottle.
All-in-all it's a cute bottle that I will probably leave at my bedside table and use my smaller water bottle so I can carry everything.
