If you don't need a bunch of storage, the Camelbak Menace (Outlaw Series) is a good recommendation. 70oz bladder w/ insulation around hose. It is made for back country skiers so it is lightweight and holds close to your body with two front clik straps. There is also a designated location for probes, shovel, and shovel handles. I love getting back to the truck at the end of the day and forgetting it was even on.
