Canteens and Hydration Bladders

Hydration is basic stuff to anyone leaving home. The older way is to carry a water bottle, but nowadays you have a choice between a bottle and a very handy water reservoir.

Water bottle

A basic canteen or a more modern water bottle is easy to pack, use, and clean. Usually takes around 1 liter (quart) of water. We've got both army surplus canteens and new canteens and water bottles.

A good companion to a drinking bladder because it's much easier to pour out water from a bottle than from a bladder.

Hydration pack

Ahh, the modern way of drinking on the move is of course the hydration pack. Although water containers carried on the back are an age-old invention, at some point someone decided to add a tube to it so the water could be quaffed directly from the reservoir.

The hydration pack and hydration reservoir are kinda two different things; the pack usually means the combination of a bladder and its carrying pack or the pack only. The reservoir means the bladder itself.
