I was just shopping at Big Lots. In the camping equipment, this store had Camel Pack water carriers under a different brand name. This is called simply, Hydration Bag. Best thing; these are only $8.00. Not all Big Lots will have them, you might have to shop around. There were six left at the E. Capitol Dr. store in Milwaukee. It seems to be decent quality, but I haven't tried mine yet. I thought If anyone heading out to Santa Barbara could stop by a few Big Lots stores and pick up some, I bet the volunteers deployed there could certainly use them considering the temperature reports I've been getting off The Weather Channel.
