oh wow those kriega backpacks look hardcore! how does it breathe? will I die in the Tulsa heat? I tried on a MULE camelbak an it was ok, it was 90 dollars at academy, kinda pricey for what ya get. I can ghetto rig a bladder into my backpack for that price! hahah, thats not my style though! all those look pretty nifty, thanks for the help thus far, and any more suggestions are welcome! BTW, anybody in the Tulsa area that goes biking? looking for some new places to go.
