Looking for Professional Cornhole bags to play in ACL events? The Ultra Cornhole Viper-B is just like the Viper but the slow side has a bit more grab to it. If you are looking for the same type of amazing flex as the Viper but want a little more stick on the slow side, look no further. This bag has amazing graphics on both the fast and slow side. You know it is the slow side because that's where the two big stars are. We always put stars on the slow side unless it is made from a hybrid "carpet" material like our Viper-R which can't handle the heat of sublimation.
