I love having water when I need it.
I use the camelpac mule has plenty of room for stuff
on chilly days I can stuff a lite jacket in it .
on hot days I can cool my face and my riding partner and still have plenty of water. during the winter and summer I blow the water out of the tube. there is a kit that keeps it cool in the summer and helps keep it from turning into ice during the winter
NEVER wait until you are thirsty to drink.
with the hydropac (sp) I can fill a water bottle with a power drink
(yuck) and cut it with water in my mouth. and the mouth piece
is always close to my mouth (I can take a drink with out taking my hands off the bar.
