I have carried my black bal in pouring rain (not just sprinkles) and it just made it smooshier and softer! I even spilled a half of a bottled water in my magenta and you truly can't tell. That is the beauty of these bags, they actually look better with use, and in my case, hard use! I encourage you to use them and enjoy them regardless of the weather!
really??? your pour magenta! but good to know it can hold up in the pouring rain!
