The Bridgestone J40 Dual Pocket Cavity irons are built on Bridgestone's innovative weight management system and are designed for players that want great feel and a traditional look but need help squaring the clubface at impact. The midsized head is forged from 1020 mild carbon steel and produces a mid-to-high ball flight whilst the revamped dual pocket cavity provides Tour-like stability by redistributing weight to the perimeter, increasing the J40's MOI. Bridgestone have also improved the club's leading edge to help prevent the irons digging in softer conditions.
