Description
U.S. Kids Golf UL39 (99cm) WT30-S junior irons, graphite
The U.S. Kids Golf UL39 (99 cm) WT30-S junior wedges from the DV3 series are purpose-built for the youngest golfers standing between 92 and 106 cm tall (approximately 3–4 years of age). Engineered from the ground up for small players, these clubs deliver more precision, more forgiveness, and greater stability at impact — making them the ideal first step in the short game. Available as a Pitching Wedge (PW, 48°) or Sand Wedge (SW, 56°), in both right-hand and left-hand versions.
The WT30-S designation means the club heads are a full 30% lighter than standard adult irons. A wider sole and a lower centre of gravity work together to help the smallest players launch the ball into the air with ease, while the improved heel-to-toe weight distribution keeps shots on line even on off-centre strikes. The K-Flex graphite shaft with a low kick-point is tuned specifically for the slower swing speeds of very young golfers, and the grip is sized precisely to fit small hands.
Key Features
- WT30-S Club Heads: Heads are 30% lighter than adult-standard irons, making it dramatically easier for young players to generate club head speed.
- Wide Sole Design: A broader sole lowers the centre of gravity and glides smoothly through turf, helping beginners get the ball airborne with confidence.
- Enhanced Forgiveness: Optimised heel-to-toe weight distribution significantly improves stability on off-centre hits, keeping shots on target.
- K-Flex Graphite Shaft: Ultra-lightweight graphite shaft with a low kick-point is tuned for the slower swing speeds of 3–4 year-old players.
- Low Kick-Point: Promotes a higher, easier ball flight that is ideal for junior short-game development.
- Junior-Sized Grip: Correctly sized grip matched to small hands encourages proper technique from the very first swing.
- Two Loft Options: Available as PW (48°) for approach shots and SW (56°) for bunker and chip play, covering all short-game situations.
- Left- and Right-Hand Versions: Both orientations are available so every young player can start with the correct equipment.
- Optimal Height Range: Designed for players standing 92–106 cm tall (approximately 39–42 inches), ensuring correct club length and swing mechanics.
Technology in Detail
WT30-S Ultralight Club Head
The WT30-S model features club heads engineered to be 30% lighter than comparable adult irons. This dramatic weight reduction allows the youngest players — typically aged 3 to 4 years — to swing the club naturally without fighting excess weight or developing compensatory bad habits. Lighter heads promote faster, more efficient swings and help young players achieve the optimal launch angle for their short-game shots. Every component of the WT30-S head is precisely balanced to encourage a consistent, repeatable motion from the very beginning of a child's golfing journey.
Wide Sole and Low Centre of Gravity
The wider-than-standard sole of the UL39 WT30-S iron does two things simultaneously: it lowers the centre of gravity closer to the ground, and it increases the effective footprint of the club head through impact. A lower CG means the ball launches more easily and at a higher angle, even for players who are still learning a proper swing. The broad sole also glides through the turf cleanly rather than digging in, which is especially valuable for young golfers hitting from grass for the first time. The result is a club that is genuinely forgiving and confidence-inspiring at every level of junior play.
Heel-to-Toe Weight Distribution for Forgiveness
Young golfers rarely hit the sweet spot every time — and the UL39 WT30-S is designed around that reality. Weight is distributed across the heel and toe of the club head, increasing the moment of inertia (MOI) and reducing the twist of the face on mishits. Shots struck away from the centre still produce usable ball flights, helping young players stay motivated and build their skills without being discouraged by the penalties of off-centre contact. This forgiving architecture supports healthy long-term development of a consistent short-game technique.
K-Flex Graphite Shaft with Low Kick-Point
The lightweight K-Flex graphite shaft is specifically engineered for the low swing speeds of very young players. Its extra-flexible profile stores energy throughout the downswing and releases it efficiently through impact, helping generate ball speed that would otherwise be impossible with a stiffer or heavier steel shaft. The low kick-point — the point of maximum flex along the shaft — ensures that the stored energy translates into a high, soft-landing ball flight well-suited to short-game situations around the green. The ultralight graphite construction also reduces total club weight, making practice sessions more comfortable for small arms and shoulders.
Correctly Sized Junior Grip
Using a grip that is too large forces young players to compensate throughout the swing, leading to poor habits that are difficult to correct later. The UL39 WT30-S comes fitted with a junior-sized grip scaled precisely for hands in the 3–4 age range. The correct grip diameter promotes a natural hold, proper wrist action, and a square club face at impact — all fundamental building blocks of a sound golf swing. Starting with correctly fitted equipment from the very first club gives junior players the best possible platform for long-term enjoyment and improvement.
Two Wedge Options — PW and SW
The UL39 WT30-S short-game set covers the two most essential scoring clubs: the Pitching Wedge (48°) for controlled approach shots and standard chip-and-run situations, and the Sand Wedge (56°) for bunker escapes and higher-lofted pitches around the green. Having both lofts available in a matched, properly fitted set means young players learn to choose the right club for each situation — an important cognitive and strategic skill that forms the foundation of a complete golf game. Both clubs share the same head weight, shaft, and grip specification, ensuring a consistent feel and swing across the short-game set.
