Everybody needs a water bottle on our rides, and this bag does more that just hold it. It is waterproof and has a small extra pocket for another small neccesity (ie. Keys, cell phone). It is insulated to keep the temperature in the water bottle what you want it to be, and is easily attached with a nylon strap and side release buckle. It also has a carrying strap for when you are off the horse, as well.
