The 2027 DeMarini Velvet Thunder D54 is a maple wood composite bat: a pro maple exterior for a true wood crack, reinforced by a one-piece internal composite rod for durability and year-round use. The D54 turn has a thick profile for more barrel surface, with a cupped end, a slightly end-loaded swing weight, a -3 drop and a 2 5/8-inch barrel. A tapered wood composite handle with a textured topcoat gives grip and bottom-hand leverage. BBCOR and Perfect Game approved. Sizes 31-34 in, with a limited 1-year manufacturer's warranty.
