I bought this cooler used from a friend and I never used it. It’s 100% waterproof and very thin. Would be a great thing to have at a show or an endurance ride while you’re standing around with your horse tacked up in pouring rain. Like I said, I never got to use it and I’m selling it for just $10 cause I noticed there are a couple spots on it that seem sort of splotchy for lack of a better word. Does not seem to affect the integrity of the waterproofing or the blanket and definitely has no holes or tears.
