Yonex Astrox 3DG, series is a popular line of head-heavy, high-tension attacking rackets built with Durable Grade (DG) technology. This specialized framing enables the rackets to handle extreme string tensions up to 35 lbs.
The series splits into two distinct variants to cater to different player preferences: the ST (Stiff) model for advanced players wanting a solid, quick-repulsion hitting feel, and the HF (Hi-Flex) model for beginners and intermediates seeking maximum whip and arm comfort.

Core Technological Features
Both rackets utilize Yonex’s signature performance technologies to optimize heavy smashes and fast handling:
- Durable Grade (DG) Frame: Built from Super High Elasticity High Modulus Graphite. It safely withstands ultra-high string tensions up to 35 lbs, giving power hitters tighter strings for a lightning-fast response.
- Rotational Generator System: Applies the theory of counterbalance by distributing weight across the grip end, frame top, and T-joint. This allows seamless transition between heavy offensive smashes and rapid defensive recoveries.
- Nanomesh NEO: A material innovation in the shaft that enhances frame strength, ensures a quicker snapback, and maximizes energy transfer directly into the shuttlecock.
- Aero+Box Frame: Combines aerodynamic contours for faster swing speeds with a box shape structural profile to keep the racket stable through high-impact hits.
- Isometric Head Shape: Squares the frame layout to enlarge the sweet spot by 7%, significantly reducing power loss on off-center hits.
