MKids Pro Junior Green 57" (145cm/9-11Y) junior irons

The MKids Pro Junior Iron (Green, 57"/145 cm) is the premium individual iron for young golfers aged 9–11, representing the highest-specification junior club range on the market. Engineered with the developing golfer firmly in mind, these irons pair club heads sized at 95% of standard adult irons with genuine Tour-quality grip and shaft technology — delivering the same feel and feedback that serious junior golfers need to build their game with confidence. Available in left- and right-hand versions and in 5-, 6- and 7-iron configurations, they allow parents and coaches to add exactly the right club to a junior's bag.

The Green colour-coding identifies the 57"/145 cm size tier, making it straightforward to match the correct club length to your child's height. As part of the MKids Pro line, every iron in this range features the Grafalloy ProLaunch graphite shaft and the MKPro Tour Style grip — components chosen to help young players develop proper mechanics from the very first swing.

Technology in Detail

Specifications

Shaft: Grafalloy ProLaunch

MKids® worked closely with Grafalloy® — world leaders in golf shaft technology — to develop the ProLaunch shaft exclusively for the MKids Pro junior range. The collaboration centred on using launch-monitor data to tune every aspect of the shaft's performance: flex profile, kick-point location and torque rating are all optimised for junior swing dynamics rather than adapted from adult specifications. The outcome is a shaft that delivers optimum carry distance, a high launch angle and low torque for outstanding shot-to-shot consistency — qualities that help junior players see genuine improvement as they develop.

Grip: MKPro Tour Style

The MKPro Tour Style grip is unique to the MKids Pro range and is produced by MKids® in a variety of sizes to match each club-length tier. For the Green 57" tier, the grip is sized to fit junior hands precisely, encouraging the correct finger placement and a light, pressure-free hold. This seemingly small detail has a significant impact on long-term development: a grip that is too thick or too thin leads to compensatory movements in the wrists and arms, whereas a correctly fitted grip allows the swing to function as intended. The Tour-quality materials ensure durability and all-weather performance, so the grip performs as well on a damp autumn morning as on a dry summer day.

Sizing & Fit Guide

Getting the right club length is the single most important fitting decision for a junior golfer, and MKids® have made it straightforward with their colour-coded size system. The Green range corresponds to a player height of 57"/145 cm, which typically aligns with children aged 9–11 years — though height should always be the primary guide rather than age. Clubs that are too long force the junior to adopt a flat, sweeping swing plane, while clubs that are too short produce an overly upright, cramped action. A correctly fitted set allows natural, athletic posture and consistent ball-striking from the start.

The MKids Pro range is available in three colour-coded size tiers in total, so as your junior grows there is a straightforward upgrade path that keeps equipment matched to their physical development at every stage of their golfing journey.
