Yonex EZONE 100SL (2025) -- Blast Blue [Frame Only]
Overview
This is the Yonex EZONE 100SL -- the 2025 super‑light (SL) version of the EZONE 100 line, available in "Blast Blue." It is designed for intermediate to advanced recreational players (or juniors stepping up) who want an adult‑sized head with easier manoeuvrability and reduced weight. As a frame‑only model, it provides flexible customisation in grip, stringing, and tension, allowing players to tailor it to their style.
Key Technologies
ISOMETRIC? Head Shape
Yonex's signature racquet head design increases the size of the sweet spot (especially off‑centre) for more consistent power and forgiveness.
Minolon / 2NAMD Speed Composite
A mix of ultra‑thin, flexible Minolon fibres and 2G NAMD SPEED Graphite material helps boost energy transfer and stability, and reduce harsh vibrations on impact.
Beam Geometry Updates (2025)
The upper hoop has been thickened, with a groove on the inner frame for improved bending behaviour -- enhancing stability without drastically increasing weight. This results in more pop and better control compared to earlier light models.

Pro / Player Review
Strengths: The EZONE 100SL offers excellent manoeuvrability for its head size, which helps generate decent racquet head speed -- especially useful for players who prefer not to wield the full‑weight EZONE 100. The updated beam geometry adds stability and improves control over shot dispersion. The feel is more forgiving, with reduced harsh feedback, thanks to the Minolon fibres dampening vibrations.
Weaknesses: Due to its lighter construction, it offers less plough‑through compared to heavier frames. On powerful, flat shots -- or when requiring a full backswing -- you may find it lacking in mass. The lower unstrung weight may necessitate adding overgrip or lead tape for increased stability or balance. Additionally, lighter frames tend to wobble slightly more under heavy load (e.g. hard serves or volleys) compared to stiffer, heavier models.
Suitability: Ideal for intermediate players seeking a lighter, arm‑friendly racquet; juniors transitioning to adult frames; or club players with slower swing speeds who benefit from easier power access. However, players accustomed to heavier, stiffer frames may find this one too flexible or lacking in plough‑through.
Comparison: Compared to the standard EZONE 100 (≈ 300 g unstrung), the 100SL is significantly easier to swing and less tiring to use. Compared to other low‑weight models, it offers solid comfort and stability, thanks to Yonex's materials and frame design -- though it may not match the raw power of some stiffer alternatives.
Q: Is this frame good for players who suffer from elbow or shoulder issues?
A: Yes -- the lighter weight and vibration‑dampening features (Minolon fibres, composite design) make this frame more arm‑friendly than heavier, stiffer rackets. However, string choice and tension still play a crucial role: opting for a softer string or hybrid setup, and avoiding excessive tension, will further help reduce shock.
Q: How does this frame perform for spin?
A: The 16×18 string pattern provides a reasonable blend of control and spin. While it's not as open as 16×19 or 18×20 frames, the slightly lighter weight aids rakuet head acceleration, which supports spin generation. If spin is a priority, use a spin‑friendly string with slightly lower tension.
Q: Given that this is "frame only", what should I look out for when stringing/gripping?
A: Be sure to choose a grip size that suits your hand comfortably -- overgrips can be added if needed. For strings, consider the type (e.g. multifilament for comfort, polyester or hybrid for durability), and do not overtighten -- over‑tensioning a light frame may result in a harsh feel. You can also adjust the swingweight with additions like lead tape, if you find the racquet lacks depth or stability.
