Cobra's J-Speed Series comes in two sets for players aged 6-8 and 9-11, and the clubs are engineered with the same computer-aided design programs and materials as Cobra's adult clubs. The 6-8 year-old set features a 300cc J-Speed driver, Baffler hybrid, stainless steel 7-iron and wedge, putter, lightweight stand bag with dual carry strap and a J-Speed cap. The 9-11 year-olds also get a J-Speed fairway metal, and the 7-iron is replaced by a 6-iron and 8-iron.
