The soft, flexible Salomon Active Handheld water bottle will keep you hydrated and energized on all your short runs. Just carry the water you need and nothing else.
Simple handheld water bottle, very easy to use. I wish it had a pocket to hold nutrition! 17 oz, which doesn't last long, but nice to have to supplement a hydration vest. It is velcro adjustable so I attach it to my vest once it's empty!
