My frustration with my camelback is the effort required to aspirate the water from the bladder via the tube and valve. First you have to bite on the valve to open it, then you have to suck in to drink. A pressurized system such as yours seems like the ideal solution...
I'm going to do some more reading on your site and come back with with a few questions.
The first question would be regarding the optional filter, so you don't need to find potable water to refill the bladder, you can refill from a stream and drink?
Would you be able to post videos demonstrating the drinking system in action?
