Fist Handwear

"I first met Kai and Saya through FIST supported Olympic athlete Caroline Buchanan, the first thing that stood out for me was their direct contact and professional engagement with their fans.


This is a pillar in which Fist Handwear has built its brand on in a very competitive environment. The values they have, and the way they conduct themselves with aligns to Fist and is the reason I chose to support them."

DK Australia

"After a brief chat with Kai and Saya Sakakibara I knew right away we needed to have them join the DK Family.


Since having both siblings on board they have really shown what the DK name is all about, they work well with fans, present themselves well in public and have pushed our brand far and wide around the world.

We couldn’t think of better people to help represent our brand on and off the track."
