Just received my new Thirsty Rock hydration TankBag and am truly impressed by the quality of design and workmanship of the product. Originally saw the ThirstyRock Product at our National Road Glide Gathering (aka Shark week), and though I did not win one as a raffle item, I set my sights on getting one for my long distance riding, especially for here in Colorado where the air is dry and the altitude quickly evaporates any hydration. I aam looking forward to the actual first use.
