Another great hydration pack from CamelBak is the Magic pack. Designed for women, curved shoulder/sternum straps extend rider comfort. Medium water storage capacity at 72 oz. blends with 200 cubic inches of cargo space. This leaves room for patch kits and inflation tools that off road riders need. An upper flap, over the hydration reservoir, is large enough to hold an MP3 player or phone. Trail or long distance rides won’t leave you thirsty and chapped with a Magic on your back.
