I tested the most recommended collapsible travel water bottle! I have struggled to find a collapsible travel water bottle I like so when this one kept popping up I decided to try it out! I took this for my weekend trip to and overall I would give ir an 8.5/10. It has some nice features as well as the air valve which I have never seen before. While I did have issues with it, it performed better than any other one I have tried and I will continue to bring it until I find something better!
