"add one straw, and shake violently" - Review of CamelBak 1L Bottle w/ Big Bite Valve

i will be honest, i bought this bottle to use at work and have not really put it "through the ringer" outside at this point. BUT, you need to stay hydrated if you play outside on a regular basis and having a straw for some reason helps me to drink a lot more water during the day than if i just have a wide mouth Nalgene and have to unscrew it all the time, dump water down my shirt, or let dust and whatever other randomness flies through the air fall in there if i leave it open. I have at least tested the leak-proof-ness by turning upside down and shaking violently. seriously, it was violent. And mine passed that test.
