This cornhole set is lightweight, but sturdy enough for a rock solid surface that doesn't bounce and vibrate when the bags hit. I think they will hold up well to some mild moisture. Only small issue was the velcro straps are cheap, and came off. I'm not sure if these were just for transport in shipping, but it is easy enough to staple on new velcro if I ever decide to take them from my back yard. 

Pros: Great value!
