I am deciding whether to take my hydration pack or water bottle on a bike ride coming up soon. I tend to find that when I wear my camel pack I get a big sweat patch behind it, and when i use a water bottle, the water doesn't stay cold for long.

so i am switching back and forth between my camel pack and the old fashioned bottle on the frame.

what do you rather and what are the pros and cons of each?
Do you have a different way of keeping hydrated while riding?

thanks in advance.
