The 2021 Titleist Pro V1 golf ball was a redesign featuring a softer urethane cover, a reformulated solid core, and a new dimple pattern for longer distance and improved green side spin. The ball is a premium performance model suitable for a wide range of players. KEY FEATURES: Reformulated core: A 2.0 ZG Process solid core was engineered for increased distance and higher ball speed. Faster casing layer: A new high-flex ionomer layer, originally developed for the, Pro V1x Left Dash ,adds speed and lowers long-game spin. Softer cover: A softer cast urethane elastomer cover formulation increases greenside spin for more control and provides a softer overall feel. New aerodynamics: The 388-dimple spherically-tiled tetrahedral design was the first major dimple pattern change since 2011, created for consistent and penetrating flight. Penetrating trajectory: Compared to the 2021 Pro V1x, the Pro V1 flies lower and spins less, making it a good choice for players who prefer a more penetrating ball flight .
