2 1/4 Inch Barrel Diameter 13 Inch Barrel Length Balanced Optimized Player Weighting Two-Piece, All-Composite Slow Pitch Bat Colorway: Orange | White | Grey Easton MAKO 13" Balanced Dual Stamp Slow Pitch Softball Bat: SPEM13B Commonly referred to as one of the best baseball bats of all time, Easton is reintroducing the iconic MAKO as a 13" Balanced Dual Stamp Slow Pitch Bat! Bat Benefits The MAKO is a two-piece, all-composite bat with a balanced swing feel. Contact hitters and power hitters alike will be able to swing this bat and experience the best Easton has to offer! The barrel is constructed from Thermo Composite Technology (TCT) creating softer compression for optimal performance out of the wrapper. If that wasn't enough, the MAKO 13" is equipped with an extra stiff Zero Strain 1431 Handle to maximize energy transfer and reduce vibration on mishits. Last, but certainly not least, the bat is going to be called a "dual stamp" bat as it will feature both the USA Softball (ASA) and USSSA (New NTS Tested | 240 Compression Stamp) slow pitch stamps. USA Softball and USSSA are the two largest governing bodies of slow pitch softball in the United States. By having these two stamps, the bats should be permitted for use in just about any league out there. As well, the bat will also feature the NSA & ISA stamps.
