YONEX NANORAY Z SPEED
2019 – PRESENT
Sung Ji Hyun is currently using the Yonex Nanoray Z Speed. She is using the lime yellow variant. The bright orange version of this racket has been discontinued by Yonex.
YONEX DUORA 10 LT
Yonex started sponsoring Team Korea in January 2019. She was using a Duora 10 LT at that time. The Duora 10 lt is the 4U version (83 grams) of the much more popular Duora 10 racket (available only in 3U and 2U).
The Yonex Duora 10 was launched in 2015. This racket is one of the innovative designs brought by Yonex to the industry. This was the first racket to have a frame which has a dedicated side for backhand and forehand. So, bad news for players who turn their grip during a rally.
The racket has a stiff shaft and is extremely fast in the air. The racket feels like a little head heavier version of the Arcsaber 11.
