Rawlings Pulse basketball is an indoor / outdoor composite leather all-court ball featuring an Ultra-tack composite leather cover for durability and feel. With the addition of Padded Zone Technology, in which a neoprene foam layer is hand-laid in between the cover and the carcass layer, you get a ball with both a soft feel and deep skived wide channels for maximum grip. The 100% butyl bladder gives the Pulse great air retention over the life of the ball.
