The U.S. Kids Golf UL7-42 W25 is the seventh generation of the legendary Ultralight series — the most advanced junior golf set U.S. Kids Golf has ever engineered. Designed specifically for beginner to intermediate junior golfers standing between 107 and 114 cm (42–45 in.) tall, this four-club set gives young players aged around 5 years everything they need to learn the game with confidence, from the fairway to the green. The white/pink color scheme makes it a perfect first set for young girls stepping onto the course for the very first time.
Every element of the UL7-42 W25 — from swing weight and shaft flex to clubhead loft and design — has been meticulously optimized using TrackMan technology and thousands of real data points gathered during development. The result is a set that maximizes launch, straightness, and long-term player development from the very first swing.
The W25 designation means every iron, wood, and wedge in the set features a clubhead that is 25% lighter than a comparable adult club. This dramatic weight reduction lowers the effort required to generate clubhead speed, allowing young beginners to produce a natural, free-flowing swing rather than forcing or over-swinging. Lighter heads also reduce the risk of fatigue during practice sessions, helping young players stay focused and develop correct technique from day one.
The K-Flex graphite shaft is engineered specifically for junior swing speeds, providing a highly flexible profile that stores and releases energy efficiently at impact. The result is higher ball flight and greater carry distance even from the slowest of swing speeds — a critical factor for confident, enjoyable play. Graphite construction also significantly reduces vibration and shock transmitted to small hands and wrists, making every shot more comfortable. The Sandhills Putter uses a steel shaft for the additional control and feel needed on the green.
Every club in the UL7 series was developed using thousands of real data points captured with TrackMan launch-monitor technology — the same professional system used by tour players and elite coaches worldwide. Loft angles, lie angles, club lengths, and swing weights were all validated through this process to ensure that the 42-inch size bracket delivers maximum distance, launch height, and shot straightness for players in the 107–114 cm height range. This scientific approach means the clubs genuinely fit the player, rather than forcing the player to adapt to ill-fitting equipment.
Within each U.S. Kids Golf size range, every element — swing weight, shaft flex, clubhead design, and grip size — works together as a perfectly balanced system. Using correctly sized clubs builds repeatable swing mechanics from the very beginning, laying the foundation for a lifetime of improvement. Switching to a taller size too soon, or mixing in adult clubs, forces young players to compensate with their technique and can actually slow development. The UL7-42 W25 set keeps everything in perfect harmony for the 107–114 cm player.

The UL7-42 W25 set is designed to grow with the young golfer. As skills develop, additional clubs are available to complement the core four: a Driver, 4-Hybrid, 9-Iron, Sand Wedge, and driver/pitching wedge training clubs with training grips can all be added to fill out the bag. U.S. Kids Golf's 6th Club Free program also offers options for families looking to expand the set at reduced cost. When your junior outgrows the 42-inch size range, the full UL7 system is available in larger sizes all the way up to 63–66 inches, ensuring a perfect fit at every stage of development.
