Camelbak's "bite valve," a straw lid with a plastic housing that must be bitten to allow water to be sucked out, takes a bit of getting used to, but it works well and quickly becomes natural.
Must have "BPA-free" printed on the side of the bottle.
The Podium Bottle features a pliant polypropylene body and a sport cap that twists to open. Water is released at the speed one would expect from this type of cap, making its graduated opening settings somewhat superfluous. The bottle's dial settings become firm near the beginning and end of the turn, making securing the valve in a fully open or closed position slightly awkward. There is no clear advantage of this lid type over the standard pop-up ring lid typically seen in biking water bottles, particularly as the latter can be opened with the user's teeth.
Hardness is not necessarily equivalent to durability, as this bottle proves. The bottle suffered no damage when dropped on its lid.
