Sounds like you got a good deal. What model CamelBak® did you get? I think PRICEPOINT.COM has the M.U.L.E. on sale for around $40.00, thats a heck of a deal!
The classic rocks... I can sqeeze... a huge multitool a patch kit a tire lever 3 zip ties 1 Gu gel all into the little pocket. Plus I can attach my parents' cell phone onto the strings in the back (using a little case) along with a ventilated jacket (Fox jacket... the best peice of clothing I own). I think I'll attach my own little waist belt though. The sternum strap allows for too much movement...
