Review on Collapsible BPA & PVC Free Hiking Water Bottle: Hydrapak Stash For Backpacking Adventure! by Evan Beougher

I was very excited to get my water bottle. I travel a lot and wanted something that I could easily take with me on the road. When I got my water bottle, I spent 10 minutes trying to open it. Finally, probably by magic, it opened. Once open, the bottle looked pretty good. I like the hard plastic on top and bottom, it evens out the collapsible nature of the rest of the bottle. I then decided to "fold up" the bottle so I could try to reopen it. That was a rookie mistake. After another 10 minute, and several curse words later, I was unable to get the bottle reopened. As excited as I was about this, I will be returning the water bottle. So unless you are some kind of wizard, beware this is extremely hard to open once collapsed.
