The DeMarini Zen is a solid USA bat option built around a two-piece all-composite build and Dark Matter Composite Barrel, with a balanced swing weight for consistent contact. That composite construction is tuned for barrel performance once broken in, and Anomaly Connection helps reduce harsh hand feedback on mishits. Anomaly End Cap supports barrel control and energy transfer through the zone. Available in -10 drops, with lengths from 29-31 in, certified for USA Baseball play.
