if i were oprah, and if i had a list of my favorite things, my camelbak water bottle would be top on my list. i love it, simply love it. this is saying a lot, because i do not enjoy drinking water. but with this patented water bottle i am now refilling it multiple times a day. i think it is the straw that has me sold. it is spill proof, time proof and dummy proof. the bottle is bpa free too. in fact, i will be buying one for my entire family this Christmas.
