I would absolutely give this 5 stars but the zipper starts on the wrong end. The way its made, to zip it closed, I have to zip it over the top of my Yeti tumbler. On my other bags, the tumbler is on the end where the zipper closes. This bag is very tall so maybe the designer didnt think it would matter. But i have 2 tumblers that the straw is VERY tall so I cant zip the bag closed. Everything else about the bag is absolute perfection.
