Nippon N.S. PRO ZELOS 6 Iron Shafts Steel - .370 Tip

Nippon N.S. PRO ZELOS 6 Iron Shafts

The Nippon N.S. PRO ZELOS 6 Iron Shafts set a new benchmark as the world’s lightest steel shaft, weighing approximately six grams less than the already-featherweight ZELOS 7. Designed with Nippon’s exclusive NZNS 60 alloy, this shaft delivers the control and consistency of steel while rivaling the launch, spin, and carry characteristics of lightweight carbon options. Ideal for players seeking effortless speed, it maximizes initial velocity and launch without compromising on feel or direction.

Engineered with a smooth, low-resistance bend profile, the ZELOS 6 enhances timing and energy transfer—even for players with slower swing tempos. Its refined responsiveness gives golfers of all skill levels easier contact, improved accuracy, and a buttery-soft impact sensation. Whether you're upgrading from heavier steel or stepping up from graphite, the ZELOS 6 offers the perfect blend of lightweight explosiveness and traditional steel control.
