Running for extended periods of time is difficult if you don't have water, but water is difficult to carry, never mind your phone and keys. The Runner combines all your essentials in one package that straps firmly onto your hand for easy carrying. But it's not so good for running.
You can't go out on a run without your keys—or your phone, money, water, and energy gels—but carrying that stuff is annoying. The challenge gets a bit easier with the handy pocketed strap on the Runner by Clean Bottle, which attaches to a water bottle for easy access and portability.
I like the idea of having a go-to water bottle. I've tried several, all of which had their strengths and weaknesses. But all of them, with time, ended up getting a little funky at the bottom. Enter, the Clean Bottle.
