Product Description

The Yonex Astrox Lite 37i is an ultra-lightweight badminton racket designed for players who want rapid racket handling, quick transition between shots, and powerful smash potential without fatigue. Weighing around 78 ± 2 g (5U) and balanced toward the head, this racket offers excellent manoeuvrability and explosive swing speed, making it ideal for fast doubles rallies and all-round attacking play.

Built with premium HM graphite and cutting-edge Yonex technologies such as Nanomesh NEO and Aero-Box Frame, the racket reduces air drag and helps the shaft restore quickly after contact — enabling faster reaction times during dynamic rallies. The ISOMETRIC head shape increases the effective sweet spot, improving consistency across smashes, clears, and drives, and the built-in T-Joint and Control Support Cap enhance stability and control for confident shot execution.

Whether you’re pushing for sharp smashes, fast net play, or quick defensive responses, the Astrox Lite 37i is a versatile choice for intermediate and enthusiastic players seeking that extra edge in speed and precision.
