Drinking water while running is probably not the best solution for hydrating your body, especially if the water is cold, but this is an interesting sports gadget. It’s called the Wrist Strapped Water Bottles and is a set of two small water bottles that you can keep around your wrist while jogging and drink from them whenever you feel very thirsty.
Each of these containers can hold 5.5 ounces of water that can be easily frozen. The bands are washable.
You can find them at Opulent Items at a price of $15.
