Product Reviews

After you get over the sticker-shock and use this product, you will find it to be very nice.
I am not a fan of the bite valve, although I don't know of any bite valve that I love. The big advantage (which I thought originally was kind of dumb) is this pump. It puts air into a thin separate compartment, NOT in the water section. When you bite the valve, you get an even flow of water with no sucking necessary. Really nice when breathing hard (or hydrating the dog)
Being able to easily turn your bag inside out is a huge plus but nothing has sold me more on this hydration system than the open/close system - simple, fast, any environment, zero user error issues.

Does this have the thumbscrew valve or push button valve (for the air pressure)?
