In a unique field test, a 9 foot alligator chomped on our reusable bottle for 10 minutes. Result? It took a while to get the bottle away from the gator, but it had no punctures. So if you are not in a fight with a gator, we believe the bubi bottle will handle your gym or book bag well.
We also shot the bubi bottle with a 9mm, and well the bullet went through the bottle, which is extreme, but it did not leak until squeezed.
