While they're staples in the mountain-bike community, most roadies eschew hydration systems in favor of the age-old water bottle. The un-areo nature of most packs makes most cyclists feel encumbered. Camelbak knows this is the case and has created a few products that might be more to the liking of the road-wheeled set.

The VeloBak is a very aerodynamic hydration system tucked cleverly inside a jersey. There's barely a bump on the back and it provides 72 ounces of your favorite beverage. It comes in men's and women's sizes and we checked them out at the Camelbak booth—they look pretty great. We're going to test these out and see if the bladder is heavy during a ride or vanishes as part of the jersey.
