Anyway, i bought a Camelbak flask a few days ago

...and they are pretty great. Huge head for cleaning inside (also dishwashable). The orange juice bits don't get stuck, The straw inside the flask goes right down to the bottom of the flask, so you never get the OO floating on the top. When you shake it (to mix the OJ+OO) is doesn't leak.
As you can tell, this flask REALLY made my day. So, i just had to share it with you. lol
