Oh and I think I have found a solution to my water bottle dilemma.

Right now my bottle is 25 ounces. Well I wanted the extra almost 8 ounces. I can put the stainless steel cup in the side zipper pocket, the 1 liter ss bottle in it and then use paracord around the pull cord on the pocket and loop it around the bottle neck! I'll try it out later and see if I actually like it or not.
