Track has a longstanding history of success in the High-Performance realm with Paradox, Paragon, Archetype, and now the Criterion. Each generation of dynamic core and coverstock combinations has exceeded its predecessor for performance and uniqueness in the category. Criterion Hybrid is the follow-up that continues the legacy of these lines and offers the performance you expect. The performance starts at the center of the ball with the Criterion M.D. core body, unique for its shape and technology. However, the cover of this highly dynamic ball is what sets itself apart. The all-new Super Response Hybrid with HK22C establishes an all-new ball motion for the Track Nation, a big ball with a bigger mid-lane and backend than any other Pro-Performance ball the brand has seen.
