Wilson Defy LS V1 SE

The Wilson Defy LS V1 SE keeps last year's foam core, diamond head and high balance. Two things moved: the face now has carbon in it, and the weight is fixed at 355 g. No review of this racket exists yet. Everything below comes from the specs, and the gaps are named as they come up.

Carbon joins the face: what the SE changes against the 2025 Defy LS

The 2025 Defy LS V1 is listed with a fiberglass face, called Fiberflex. The SE is listed with carbon and fiberglass, called ComfortFlex. That is the main change.

What does it mean for you? Carbon is often stiffer than fiberglass, so the face of the SE may respond a little more crisply. That is a guess from the materials, not a measured result. The core is foam in both years. The shape is diamond in both. The balance label is high in both, and the level is Advanced in both. This is the same racket family with a different skin, not a new design.

One limit: the 2025 listing does not publish balance in millimetres or thickness, so those two cannot be compared.

355 g instead of 350 to 360 g: what a fixed weight means

The 2025 version was listed from 350 g to 360 g. The SE is listed at 355 g, with no range. The midpoint is the same, so the average racket barely changes. What changes is the spread.

With a range, two rackets from the same box can differ in weight. A single figure suggests less variation between samples. Whether production really is tighter, the listings cannot tell you. For a high-balance diamond, 355 g is not light. Weigh it against your own arm before you commit.

Foam core, ComfortFlex face: why comfort reads High and control Low

The comfort meter reads High. Two things drive it: the soft foam core and the mixed carbon and fiberglass face. Both point to a racket that absorbs shock, which matters if your arm complains after long sessions.

Control reads Low, and sweet spot reads Low. The reason is the diamond shape. It puts the weight high in the frame and shrinks the forgiving area of the head. The soft core and the 265 mm balance push control up, but the shape wins. Thickness is 38 mm, which says little by itself.

So the picture is odd but consistent: a racket that is kind to your arm and unkind to your timing. You pay for comfort with precision.

Power, comfort and control, says the product page: the meters answer differently

The product page claims accessible power, comfort and control. It calls the racket a crossover between power and stability. That is marketing language, and the meters only half agree.

Comfort fits. Power sits at Medium, which is usable but not high. Control reads Low, so the promise of control is the weakest part. The product page also talks about a manageable offensive game for intermediate and advanced players. A retailer listing tags it Advanced and as an offensive racket. If you are an intermediate player, the Low control and Low sweet spot readings are worth weighing before you believe the pitch.

Defy LS V1 SE next to the Defy V1 SE and the Defy Pro V1 SE

Two siblings from the same year show where this racket sits.

The Defy V1 SE has a 3K carbon face, high-density Power Foam and a weight of 365 g. Its meters read High power, Low comfort and Low control. It is the harder-hitting choice.

The Defy Pro V1 SE has a 15K carbon face, Power Foam and a weight of 370 g. It reads High power, Medium control and Low comfort. It is the heaviest of the three.

The LS is the odd one out. It is the lightest at 355 g, has the softest setup and is the only one with High comfort. It gives up power to get there. If your arm is fine and you want output, look at the siblings. If your arm needs a kinder racket, the LS is the one in this group that reads that way.

No review, no head size, no frame: what you cannot check

No tester has published a court review of this racket yet. Head size, frame construction, handle and weight system are not published either. That means you cannot judge the exact face area or how stiff the frame is.

The meters are calculated from the specs. They describe tendencies, not how the racket plays in your hands. If you can try one at a club or demo day first, do that. Pay attention to how it handles off-centre hits, since that is where a diamond with a Low sweet spot reading will show its limits.
