Just wanted to add a little update since I've had a change to use it on several hikes...

When I'm out on a short hike (usually to the hills near my home) I will only carry water, my PSK (which is basically a first aid kit and a few extras, nothing major) and rain gear. I will leave the Badlands Hybrid at home and carry this:



(Mine has a third row of MOLLE with loop Velcro in-between the webbing.)

It has worked beautifully as a small day pack. Very comfortable and will hold more than you think. I've added some light straps with side release buckles so I can strap a jacket on the outside if it's a bit chilly out. I'll get some pictures of my set-up tomorrow when I have a better backdrop than the floor of my office.

Anyway, I've found this pack online for as little as 25 bucks! The Mil bladder itself is worth $30. It's heavy duty with a bite valve cover and a quick-release insulated hose. I've been using the bladder in my Badlands (and a Mountainsmith Circuit) for 2 years now. It well is worth checking out!
