I never leave home w/o it.
A friend on another forum asked me how I set this up. Using a rain cover from one of my tankbags I place a cut to fit sheet of ice inside a large ziplock over a wash cloth then add soda, water or whatever, then another sheet of ice and another wash cloth to catch the condensation and tighten the drawstring. I keep it in my tankbag or side bag. I can add a bunch of grapes, a sandwich, candy/energy bar, nuts, whatever and they stay cool pretty much all day. No more cold drinks only in a gas station parking lot. Summers coming soon.
