What Mizuno Say:
Mizuno's ST-G driver is a compact, powerful player's club that offers golfers the ultimate in adjustability and performance.

With technology like the CORTECH Chamber, two convergent weight tracks and more, the ST-G is the perfect choice for golfers who demand the best possible performance from their driver.

Benefits:

• Max Convergent Fast Track - Two weights can be adjusted to create a spin range from ultra-low to mid-low.
• Compact 440cc Players Profile - The ST-G Driver s a pear shape with a modern profile that's designed to sit perfectly square at address when in the neutral
  position.
• New Beta Rich TI LFS  - Mizuno's ST-G driver s a revolutionary new face material that is 9% stronger and faster than the previous SAT2041 material. The complex
  multi-thickness face geometry is optimized for maximum ball speed across a wider area of the clubface, even on off-center hits. Tour testing has shown that the new face
  material produces an average ball speed increase of 1.5 mph, which can translate into significant gains in distance.
• Expanded Carbon Toe Wrap - Mizuno's toe-weighted carbon fiber construction in the ST-G driver unlocks unprecedented shot-shaping capabilities.
• Tour Tested for Sound - Mizuno's CORTECH Chamber and internal tuning ribs work in harmony to create a solid, responsive feel at impact, regardless of weight setting.
