The UL7-39 is the perfect starter set for the youngest golfers — beginners and intermediate players standing between 99 and 107 cm tall (approximately 3–5 years old). Every element of the set, from the lightweight graphite shafts to the correctly weighted clubheads, is precisely engineered to help young players get the ball up into the air effortlessly and develop a consistent, repeatable swing right from the very first round. The black and red carry bag keeps everything neatly together and lets junior golfers head to the course with everything they need.
Ultralight 7, or UL7, is the seventh and most advanced generation of Ultralight golf clubs engineered by U.S. Kids Golf. The result of thousands of data points gathered using Trackman ball-tracking technology and extensive product development research, the UL7 line represents the most sophisticated and highest-performing set of junior golf clubs ever produced by the brand. Within each size, swing weight, shaft flex, clubhead loft, and many more attributes work together as a matched system to maximise the young player's long-term development. The UL7-39 is the shortest size in the UL7 range, built specifically for the height and physical ability of the smallest players. As skill and confidence grow, the set can be expanded with additional clubs — including a Driver, Hybrid, Pitching Wedge, or Sand Wedge — to build a complete bag over time.
The W30 designation means the clubheads in this set are 30% lighter than a standard adult clubhead of equivalent size. For the youngest players with the slowest swing speeds, this reduction in mass is transformative — it allows them to accelerate the club through impact naturally, generating the clubhead speed needed to launch the ball into the air with ease. The correctly weighted heads also prevent overloading small arms and shoulders, reducing the risk of compensatory swing habits forming at an early age. Combined with the high lofts of the 3 Wood (26°) and 7 Iron (38°), the result is consistently high, satisfying ball flight that keeps young players motivated and engaged.
The UL7 range is the product of an intensive research and development process driven by thousands of real-world data points captured using Trackman ball-tracking technology. By analysing launch angle, ball speed, spin rate, and carry distance for young players across all height sizes, U.S. Kids Golf was able to fine-tune every specification — loft, lie, shaft flex profile, swing weight, and grip size — to deliver optimised performance for each individual player category. The UL7-39 set is therefore not a scaled-down adult club but a scientifically matched tool designed for a player of this exact height and physical development stage.
The K-Flex graphite composite shafts used throughout the UL7-39 set are engineered exclusively for the slow, developing swing speeds of beginner and intermediate junior golfers. Graphite construction keeps the overall club weight to an absolute minimum, while the flexible shaft profile loads and releases energy efficiently through the downswing, maximising ball speed at impact without requiring adult-level strength. The shafts are frequency-matched across the set, meaning the bend profile and kick point are tuned to deliver a consistent feel and trajectory from the wood through to the irons. The Sandhills Putter uses a straight steel shaft with offset, providing a firmer, more precise feel for the putting stroke.
One of the most important principles behind the UL7 line is that all clubs within a given size work as a single coordinated system. Swing weight, shaft flex, loft, lie angle, and grip size are all dialled in together so that a child's swing mechanics remain consistent across every club in the bag. Using oversized or mismatched clubs — for example, a heavier driver from a different brand, or clubs sized for a taller player — forces young golfers to compensate with their technique, leading to slower hand speed and habits that are difficult to correct later. The UL7-39 set eliminates this risk by providing a fully matched, size-appropriate system from the start.
The UL7-39 3 Wood (26°) features a low and deep centre of gravity specifically engineered to promote an easy, high-launching ball flight from both the tee and the fairway. The W30 lightweight head reduces the effort required to swing the club to an appropriate speed, while the 26° loft angle is far higher than an adult fairway wood — a deliberate design choice to ensure beginners can achieve airborne shots consistently. A headcover is included to protect the clubface during transport. The 3 Wood is the ideal distance club for young players who are not yet ready for a full driver, providing a forgiving, confidence-building option off the tee.
The UL7-39 7 Iron (38°) is engineered to provide ease of playability by positioning more mass directly behind the sweet spot for better trajectory control and high-launching distance. The wide sole design and softened leading edge prevent the club from digging into the turf, even on mishits, providing maximum forgiveness for players who are still learning to strike the ball consistently. With a K-Flex graphite shaft and a club length of 23 inches (approximately 58 cm), it is perfectly scaled for players in the 99–107 cm height range. The generous loft ensures the ball climbs quickly into the air, rewarding young players with visible results that sustain their enthusiasm for the game.
The Sandhills Putter is a mallet-style design featuring a half-moon head profile and a plumber's neck hosel that offers a generous, confidence-inspiring look at address. The wide mallet head makes alignment intuitive for young players, while the 1/4 toe hang suits a broad range of putting stroke types — from straight-back-straight-through to a slight arc. A straight steel shaft with offset is used, providing a firmer, more stable feel than graphite and keeping the hands ahead of the ball at impact for a consistent, controlled putting stroke. At 20 inches (approximately 51 cm) in length, it is correctly sized for players in the 99–107 cm height range.
The included carry bag is finished in a bold black and red colourway and is sized to match the shorter UL7-39 clubs perfectly, ensuring the clubs sit securely and do not rattle during transport. A dual shoulder strap distributes the light weight of the set comfortably across both shoulders, making it easy even for the youngest players to carry their own bag around the course — an important step in building independence and a love of the game. The bag features a personalisation pocket, allowing the player's name or initials to be added for a personal touch.
