This is a great product built with typical Camelbak quality. It's polycarbonate construction ensures a tough bottle, I've dropped this thing on concrete and asphalt more times than I can count. Even when full it won't crack. It has a convenient loop perfect for attaching to a lanyard or carabiner. It's easy to drink from when driving since the straw goes to the bottom of the bottle, you don't have to tip it up just bite and drink. The Camelbak "bite and suck" system also means the bottle won't drip even when it's upside down and open. I have the twenty-four ounce version and highly recommend this product.
