Hyper Slim Shaft:

Yonex's slimmest shaft ever features a solid core with revolutionary material, Namd, to provide greater flex and snapback performance while also reducing air resistance for faster swings. 

New Revolutionary Materia:

Utilizing high quality Namd* graphite throughout the frame produces more flex with a faster snapback, unleashing dramatic steep power.
