The U.S. Kids Golf UL42 Ultralight iron series is purpose-built for young golfers between 107 and 113 cm tall (approximately 5 years of age), giving beginners and early intermediates the best possible start on the course. Developed as the third-generation DV3 (Distance & Velocity) iron and continuously refined through rigorous Trackman technology testing, these clubs feature a wider sole, a lower centre of gravity, and a lightweight graphite K-Flex shaft — all working together to help small players launch the ball effortlessly into the air. The WT25-S head design is 25% lighter than a standard adult iron head, making each swing easier and more natural for a young player's developing physique. Available in a 9 Iron, Pitching Wedge (PW), and Sand Wedge (SW), in both right- and left-hand configurations.
The DV3 iron head is the result of extensive research and development backed by continuous Trackman launch-monitor testing — the same technology used by Tour professionals. Each head geometry was iterated and measured on the range to pinpoint the ideal loft, face thickness, and sole geometry for a junior swing. The result is a thinner face that generates higher ball speed, combined with a wider, lower sole that raises launch angle without the player needing to make a perfect strike. For a child just learning the game, that extra margin of error is transformational: more balls fly straight and high, building confidence rapidly.
By relocating the centre of gravity (COG) lower and deeper within the club head, U.S. Kids Golf engineers have made it far easier for young players to launch shots with a natural, controlled swing. The wider sole edge glides through turf rather than digging in, reducing fat shots and improving contact consistency. This lower COG also increases dynamic loft at impact, producing a higher, softer-landing ball flight that is ideal for shorter junior approach shots. The improved mass distribution around the perimeter of the face further increases the moment of inertia (MOI), so off-centre strikes still travel a useful distance.
The lightweight K-Flex graphite shaft has been frequency-tuned specifically for a young golfer's slower swing speed. A low kick-point encourages the clubhead to release early through impact, naturally adding launch and carry without requiring the player to swing harder. Graphite construction dramatically reduces the overall club weight compared to steel, making it easier for small players to maintain proper swing mechanics throughout a full round. The shaft flex is calibrated to the UL42 height range, so the timing and feel of each shot is consistent and repeatable — a key factor in skill development.
The WT25-S designation means every club head in this series is 25% lighter than a comparable adult iron head. This is not simply a scaled-down adult club — U.S. Kids Golf has engineered the weight, balance, and geometry from the ground up for players in the 107–113 cm height bracket. A lighter head allows a junior to swing at a speed appropriate for their age without over-exerting, reducing the risk of developing poor compensatory habits. The head shape is designed to look visually friendly and confidence-inspiring at address, encouraging young players to stand tall and commit to each shot.
Each iron is fitted with a Size 42 velvet rubber grip — dimensioned to match the hand size of a child of approximately 5 years old in the 107–113 cm height range. A correctly sized grip is one of the most overlooked fundamentals in junior golf: if a grip is too thick, a child cannot hinge the wrists correctly; too thin, and over-gripping causes tension and errant shots. The velvet rubber texture provides a secure, comfortable feel in all weather conditions. Replacement grips are available from U.S. Kids Golf, ensuring the club can be re-gripped as the player's hands grow.

The 9 Iron is the shortest iron in a typical junior's bag and an ideal starting point for children learning approach play from 107 to 113 cm in height — typically around 5 years of age. At 62 cm (24.5 in.) in finished length and with a 44° loft, it delivers a consistent, forgiving short-iron performance that gives young beginners the satisfying experience of seeing the ball fly cleanly into the air. The frequency-tuned K-Flex graphite shaft promotes a natural swing tempo and provides the correct amount of flex to maximise energy transfer for a junior's swing speed.
The Pitching Wedge is the most versatile scoring club for a junior golfer at the 107–113 cm height range. At 48° of loft and 61 cm (24 in.) in length, the PW is the shortest of the three irons in this series and is lightened by 25% relative to a standard adult club head. The impressively deep and wide sole — a hallmark of the DV3 head design — works together with a low centre of gravity (COG) to help beginners and intermediate preschool-age players (approximately 5 years old) lift the ball with ease. The improved perimeter weighting distributes mass across the head for increased forgiveness on off-centre strikes, while the mild offset helps square the face at impact. The Size 42 velvet rubber grip completes a club that is ready for the junior course from day one.
The UL42 Sand Wedge belongs to the proven "56° Two-Star Grind" system — a design that provides the ideal combination of versatility and forgiveness from both bunkers and all turf conditions. Featuring 56° of loft, 12° of bounce, and the 2-Star grind sole profile, it helps small players escape sand without the dreaded "chunk" that plagues young beginners: the improved sole radius and width prevent the leading edge from digging too deeply, allowing the club to glide smoothly under the ball. A lower COG and optimised mass distribution make it easier to pop the ball out high and soft, while the silver satin finish gives it a clean, premium look. Like all clubs in the UL42 series, the SW is 25% lighter than an adult equivalent, fitted with a Size 42 velvet rubber grip, and mounted on a K-Flex graphite shaft tuned for junior swing speeds. Designed specifically for players 107–113 cm tall (approximately 5 years old).
