Miken Psycho 13" SuperMax Dual Stamp Slow Pitch Softball Bat: MP13X1 Muscle out softballs with this one-piece Miken Psycho 13" SuperMax Dual Stamp Slow Pitch Bat! Bat Benefits This Psycho 13" has a one-piece, all-composite build from Miken's Dual Flex Composite material which undergoes a special layering process to improve barrel flex and performance. Miken has equipped this specific Psycho with a 13-inch barrel that will carry their SuperMax load, which will have a fairly concentrated sweet spot due to the end-loaded feel. In return, this will reward well-struck balls with unmatched distance and exit velocity. Lastly, this bat is going to be "Dual Stamped" which means it will carry both the USSSA (New 240 Stamp) & the USA (ASA) stamp. As well it is going to have the NSA & ISA stamps. Due to all those stamps being present, this bat will be legal in just about any league out there! If you have purchased the bat from us and notice a defect on the bat within that original 12 month time period, please reach out to our Bat Experts. Because of that, be sure that you save the serial sticker that comes on the bat's taper when it is first delivered.
