The 5K water bottle and belt are designed specifically for a mid/short distance run around 5 kilometers long. The bottle can be clipped to the belt, or on the user's clothes. It is designed to use with a single hand easily during a run. The optional belt holds the essentials (phones, keys, etc.) with an elastic and adjustable strap that fit more body types.
I explored many possibilities during the initial concept generation. I even thought about attaching something to the trees that could give runners access to water (didn't actually go with that idea).
