Warstic Pro Signature Series wood bats are collections created in collaboration with our big league players to match the exact turning specs, preferred stain styles, and stain colors of the bats they use in games. Adult models are made from our Pro Prime Reserve stock of maple and ash, our top 3% of wood; the same quality used by our pros. Youth models available in maple, ash, and birch. We stock these bats in the most popular lengths for fast delivery. However, if we run out of in-stock bats, standard production will apply.
