Granted, a flat reservoir such as a Platypus flask is lightweight and fits into a hydration sleeve just fine, but the beauty of the SmarTube is that it enables you to use an ordinary (and free) PET water bottle (or other plastic bottle) as a hydration reservoir. A Nalgene bottle for example weighs about 6 ounces, while the same size plastic soda bottle weighs about 1.6 ounces, a big difference. The SmarTube Drinking System works especially well from the side pocket of a pack.
The SmarTube Drinking System comes with a couple of different bottle cap sizes, a 1-liter plastic tube, tube clamp, and bite valve. The weight is 2.5 ounces. A variety of optional cap sizes are available. It works by inserting a draw tube into the bottle down to the bottom and inserting the bottle upright into a pack pocket.
I personally like to put a hydration system such as this in a side pocket because it’s a lot more convenient to refill compared to using an internal hydration sleeve. It is also easily transferable from one bottle to another of the same type.
