Abstract
A sports racquet extending along a longitudinal axis and configured for supporting a quantity of racquet string generally about a string plane. The racquet includes a frame formed of a thermoplastic material and including a head portion and a handle portion. The head portion is formed of first and second hoop regions. At least one of the first and second hoop regions includes a first set of projections extending from one of the first and second hoop regions across the string plane and engaging the other of the first and second hoop regions. The first set of projections space apart the first and second hoop regions by a first predetermined dimension to define a plurality of through-hoop region openings. The handle portion is formed of first and second handle regions directly coupled together without defining either a plurality of handle openings.
