What ONOFF Say:
The pursuit of maximum distance and forgiveness for ladies. ONOFF Labospec FF-247 was designed to provide the ultimate in distance performance and ease of use regardless of player level, player style, and power. Topped with technologies and features to make our concept of (F)ly & (F)ar – a reality for all golfers.

Features & benefits:

• Made for distance – Features ONOFFs new and original iron face structure, designed to focus on distance performance. The face features two levels of
  thickness which helps optimize the flex and repulsion of the lower section of the face. The two sections are separated by a Power Trench and combined with an L-CUP face structure, the sweet spot is positioned where players actually hit the face with the ball, creating the largest repulsion point in ONOFF history.
• Optimal center of gravity design – A heavy 110g tungsten weight covers the entire sole creating a low and deep center of gravity. This makes it easy to launch the ball in the air and reduces distance lost on miss hits by expanding the sweet spot. High trajectory equals easy big carry, easy big distance.
• Satisfying impact, feel, and sound for ladies – We are able to achieve a high performance iron that has both functionality and feel by using an orthodox head
  shape which is easy to address. This creates a sense of comfort and confidence allowing you to swing relaxed and natural. Easy forgiving distance with a satisfying impact sound and feel.
• Daiwa carbon technology high repulsion kick FF-247 – Designed to optimally match the FF-247III Head. The standard shaft is an original mid-kick shaft, designed and produced in house by ONOFF with DAIWA CARBON TECHNOLOGY to match strong lofted irons. With careful focus on the butt and mid-section, we are able to produce a shaft that allows lady players to feel the shaft load and accelerate towards impact. By creating a smooth rigidity distribution curve, the shaft is able to increase swing speed while at the same time increase stability meaning less twisting of the head on miss hits resulting in straighter and longer shots. Better impact equals more distance.
• Set make up: 7-9 Irons, Pitching Wedge, Approaching Wedge, Sand Wedge
