Okay guy's and gal's. Frankie the rookie here again with another question. How in the world does one keep water cold on a ride. As usual I went out this afternoon and started out with cold water, I even added ice before I left home. Was riding about a little over an hour. During the ride I drank about half at lukewarm. At the end of the ride drank very warm water, it was wet, but that's it. I am drinking in plastic right now. Any advise?
