U.S. Kids Golf UL7-57 (145cm) W15 junior irons, graphite

The U.S. Kids Golf Ultralight 7 (UL7) 7 Iron is purpose-built for junior golfers around 145 cm (57") tall who are just beginning their golf journey or developing their intermediate game. Engineered as the seventh generation of the legendary Ultralight line, it combines a 15%-lighter club head with a K-Flex graphite shaft to help young players swing faster, launch the ball higher, and build lasting confidence on the course. Sized for a left-handed grip, this individual iron is the ideal tool for adding precision approach shots to a growing bag.

• w15 Lightweight Head: Club head is 15% lighter than standard junior heads, promoting faster swing speed and easier launch for developing players.
• Mass Behind the Sweet Spot: Weight is strategically positioned behind the sweet spot for better trajectory control and increased carry distance.
• Low & Back Centre of Gravity: CG shifted lower and further back maximises forgiveness, helping off-centre shots still fly high and straight.
• Wide Sole & Softened Leading Edge: The broad sole with a gently rounded leading edge resists digging into the turf, keeping contact clean and consistent.
• K-Flex Graphite Shaft: The lightweight graphite shaft absorbs impact vibrations, reducing hand and arm fatigue during practice and play.
• Height-Matched Fit (57" / 145 cm): Club length (85 cm / 33.5 in.) and swing weight are precisely calibrated for players at this height, supporting healthy swing mechanics.
• Left-Hand Version: Dedicated left-handed design – no adaptation required for left-handed junior players.

Engineered for Junior Success

The UL7 7 Iron head geometry places extra mass directly behind the sweet spot and drops the centre of gravity low and back. This combination produces a higher, more forgiving ball flight even on mis-hits – keeping junior golfers motivated as they see the ball climb higher and travel farther with every practice session.

Trackman-Validated Design

The entire Ultralight 7 generation was developed using thousands of data points captured with Trackman launch-monitor technology. Every attribute – swing weight, shaft flex, head weight, and club length – works together in the 57" (145 cm) size to maximise ball speed, launch angle, and straightness for players at this exact stage of growth, supporting long-term athletic development rather than short-term compensation.
