The Maverik Caliber lacrosse shaft is Maverik's strongest shaft to date! The Caliber is made of Scandium-Titanium and features military grade strength. This shaft is a favorite among our Pros for midfielders and defensemen who are looking to play hard without worrying about the integrity of their stick. The Dual Wall Taper reinforces the center of the shaft so you can throw hard checks with confidence and the adjustable butt-end is a great extra feature. The Caliber is also the shaft of choice for 4x NCAA All American LSM CJ Costabile.
