It is light weight and comes in its own carrying case. It is easy to use. I filled a two liter camel pack in just a few minutess. Remember to give a few pumps when done to clear the device and lines. Put in its bag and you ready to go with a fresh supply refreshing water. I used a friends on an outing and now I would like to order one. I would highly recommend this to anyone who is out in nature.
