I was recently reading the 101 tips that don't suck in Mountain BIKE magazine and one of the tips says to "Kill your camel" saying that "hydration packs put extra weight on the spine". Is this anything to worry about? I was just about to make the switch from water bottle to a Camelbak Mule, so I can carry all my stuff in one nice little package and have plenty to drink. Has anyone else ever heard of hydration packs causing back problems or back pain?
Let me know what you all think about this.
