Must have bottle!
I love this bottle and use it at work and outdoors! It is very durable. I've thrown one off a 100ft cliff full of water and and it didn't do anything to the bottle! My friend shot his with a shotgun and it took 2 shots to crack it!
I wound recommend only using water in it though and don't let the water get to hot while leaving it in your car or it will start to smell like a fishbowl.
