Camelbak's not cheap - but they have also not necessary. The bottle is easy, functional, pretty, even small children can easily drink from it and it is really tight. If you do not let out are the "nipple" and then the bottle with their weight superimposed thereon. This can be done fold the yes. You can take apart everything and easy to clean. You can even put in the dishwasher. I have not found any criticisms of the bottle.
