Carrying a large amount of water with you is inconvenient, as it is both heavy and takes up valuable cargo space. With a simple water filtration system, as long as you’re traveling near a water source, you can simply pump as you go. We’ve used this little pump on multiple-day backpacking trips and have been very impressed. It features attachments that fit right on a Nalgene bottle. It is simple to use and weighs less than a pound.
