The note I received from Camelbak's PR team called their new Groove "a portable filtration device that promotes a healthy and hydrated lifestyle." By way of explanation, they wrote:
[The Groove allows you to] eliminate the purchase of disposable plastic water bottles and still get freshly filtered water – anywhere. Plus, Groove features CamelBak’s exclusive bite valve – also used by astronauts in space!
Fancy things like "portable filtration devices" make sense for astronauts, of course -- they need something to help them wash down all that freeze dried ice cream. But for the rest of us, is it possible that a plain old water bottle would suffice?
