I have the older version of this water bottle. I bought it probably over 5 years ago now. I have dropped this bottle way too many times and some how it still dosen't leak. It has weathered everything from mountain biking to running and just hanging out at the house where dogs and cats love to mess with it. I cannot give enough praise for this water bottle. It's still going strong and I'm am beyond impressed on how long it's lasted. If I ever, for some reason, need a new water bottle I will be buying this again, for sure. Thank you for making such a great product!
