BRUCE BOLT's Premium Pro Baseball Knickers were designed to be the highest quality, longest-lasting pants in the game. We used a super durable, 4-way stretch, breathable polyester mesh to keep players comfortable. The pants are below the knee with a modern fit. The waistband features non-slip silicone to keep jerseys tucked in and heavy-duty BOLT buttons and a YKK zipper that will stand up to the rigors of a long season.
