I have the camelbak asymetrix 20 which I use on my bike (pedal and motorized), running, snowboarding etc. Lots of nice details and the construction is well above any other packs I have used before. Bite piece is easy to use and no odours. I got it at Winners for $40 (normally $70-80?). Like everything at Winners, its hit or miss whether you will find a given item though.
