Review on Hydration Backpack Water Bladder Lightweight by James Auzenne

I hate taking water bottles with me on walks or hikes. I also have to take the EpiPen outside with me. This package solves both problems. The water tank is easy to use and the filling hole is very large, so you can easily add ice. The storage compartment is completely separate from the water bladder compartment, so you don't have to worry about the key being put through. The backpack is comfortable even for a person with large breasts. I like that the bite valve cover closes/seals without touching it (bite valve moves up/down to open/close, then bites off, then sucks to get water).
