TaylorMade 2019 TP5 golf balls pack more speed into their most complete tour ball. The speed layer system features four increasingly stiff layers with High Flex Material, or HFM, to increase ball speed through greater rebound. HFM is a new higher modulus material that works like a stiff spring that builds up energy when compressed and rebounds quickly to boost ball speed. The Dual-Spin cover features a softer cast urethane to increase groove interaction, giving you more spin and control around the greens.
