Best for attackers who want Viper power with a friendlier touch
Advanced attacking players who want the shape and overhead weight of the Viper with a friendlier touch, players who feel the standard Viper is too hard on the arm, and strong intermediate players who are ready to move up to a diamond shape. It suits players who want the face to help their shots rather than supplying all the pace themselves. It is not designed for beginners, for players who build points mainly from the back, or for players who want a large, central sweet spot. Those who want the driest, most explosive response should choose the standard Viper 3.1.

Overview of the Babolat Viper Soft Juan Lebrón 3.1 2027
The Babolat Viper Soft Juan Lebrón 3.1 2027 is the softer version of Juan Lebrón's Viper 3.1. It keeps the diamond shape, the 270 mm balance, the Dynamic Stability System and the 3D Spin surface of the standard Viper, but replaces the 3K carbon face with Soft Carbon and the Hard EVA core with Black EVA, and is about 5 g lighter at 365 g. The construction carries over from the previous Viper Soft 3.0, with a new reversible colorway. The result is an attacking diamond that keeps most of the Viper's punch while giving a more comfortable and accessible response.
Pros & Cons
Pros
- Strong attacking power with easier access than the standard Viper.
- Comfortable touch for a head-heavy diamond.
- Stable face with solid volleys.
- Good víbora spin with the 3D Spin surface.
- More forgiving in defense than the standard Viper.
Cons
- Less explosive than the standard Viper 3.1.
- Head-heavy balance felt in quick reactions.
- Smash needs a full swing.
- Face flexes slightly at full exchange speed.
Technologies & Materials
- Soft Carbon — a carbon twill built into the face for a more comfortable striking surface and a gentler feel;
- Black EVA — a core that compresses more than Hard EVA, returning energy to the ball and reducing vibration;
- Dynamic Stability System — a reinforced central bar in the heart of the racket that improves stability, adds power and increases control;
- 3D Spin — raised patterns on the face that help generate more spin;
- HPS (Holes Pattern System) — larger holes toward the edge to widen the sweet spot and smaller holes near the impact zone for precision;
- Syntec Pro — Babolat's grip, fitted as standard.
What Makes the Babolat Viper Soft Juan Lebrón 3.1 2027 Special
The Viper Soft combines the Viper's attacking geometry with softer materials. The Soft Carbon face flexes slightly on impact and the Black EVA core compresses more than Hard EVA, so the face absorbs part of the impact and releases power without needing a perfect swing. The Dynamic Stability System still keeps the face square on hard contact, and the 270 mm balance keeps the overhead weight that defines the Viper line.

How it Feels on the Court
Defense
The most forgiving racket in the Viper family from the back. The softer face and core help keep late recoveries alive near the back glass, and lobs reach depth with less effort than on the standard Viper.
Important
The head-heavy balance still asks for early preparation on fast balls.
Net Play
The face stays stable, and the weight gives volleys solid mass through the middle. The slightly lower weight than the standard Viper makes quick exchanges at the net easier.
Bandeja & Víbora
The bandeja can be shaped deep and low, and the medium core tolerates slightly late contact.
Advice
On the víbora, spin is good when the wrist commits, helped by the raised 3D Spin pattern.
Smash
Power is good but needs a full swing. Clean contact sends the ball high off the back glass, although with less explosiveness than the standard Viper 3.1.
Maneuverability
Moderate. The racket moves more easily than the standard Viper thanks to the lower weight, but the 270 mm balance is still felt on quick reactions.
Forgiveness
Fair for a head-heavy diamond. The sweet spot is not large, but the softer face keeps off-center hits more playable than on the standard Viper.
Comfort
The touch is medium and comfortable.
Note
Soft Carbon and Black EVA filter vibration well, which makes this one of the more arm-friendly attacking diamonds.
Conclusion
The Viper Soft Juan Lebrón 3.1 2027 keeps the Viper's attacking identity while making it easier to live with. It gives an advanced attacker a heavy overhead, stable volleys and good spin, with a medium touch that protects the arm and a little more margin in defense. The cost is some of the standard Viper's top-end explosiveness and a balance that still requires good preparation. It fits attacking players who want power with comfort; pure strikers chasing maximum pace should stay with the standard Viper 3.1.
