I have been riding road bikes for a few years. I ride to work everyday, but I just bought my 1st Mountain Bike, Novara Intrepid, two weeks ago. As a road rider I would never think of using a Camel Pack because of the heat. However, with all the bouncing around that I have been doing on the MTB it seems like it would be difficult to keep the water bottles in their cages. Do most of you use bottles or packs? Either way could you recommend a good hydration system for mountain biking?

Thank you in advance for your help.
