CamelBak Hydration packs — backpacks with built-in water carriers and drinking tubes. The must-have among high-end hikers was ”developed as a cycling product, then the military started using it because you don’t need to stop to get out a bottle to keep hydrated,” says CamelBak spokesman Josh Woodbury. ”We were a little surprised that all these spa-goers wanted them, but hey, [now] we’re a fashion statement.” With the 2003 line coming in colors like ”abyss blue,” it’s just a matter of time before CamelBak hits the runways.
