I had an interesting way of carrying my water bottles. I carried them in my pockets. I hiked in military camo BDU pants because I found them to be loose and comfortable, they breathed well when it was warm outside, and they kept my legs insulated well when it was cold. Anyway, they have those very large utility pockets on the outside of the thigh. I just slipped my water bottles in those pockets. My water was always accessible to me anytime I needed it without having to reach or take my pack off. Most people would probably find it awkward, but it didn't interfere with hiking and didn't feel awkward to me. It was different, but it worked for me.
