The viper strike is our new team favorite, this bag is a combination of our 2 favorite fabrics on the market. this bag has a speed rating of a 5/9 and performs at the highest level of play. once broken in this bag feel melty in the hand while also maintaining a very gripable feel so that it isn't to loose but loose enough around the hole for bags to not hang up on the edge.. Other brands sell this similar bag for double the price so we want to bet able to supply our customers with the same high level bag at a affordable price.
