I have a lot of experience with camelbak and will be buying one of these. It looks like it has a few innovations that camelbak does not such as the reversible bladder for easy washing/maintenance… I always hated cleaning a camelbak. The pressure is nothing new, I could always just lean back on mine or squeeze it with my arm to make it squirt but for the price this looks like a great hydration system if you want to step away from “tactical” gear and just get something normal.
