Technical Viper Soft 3.0
A diamond-shaped attacker's frame built around a softer core, aimed at left-side players who want overhead punch without the wrist-jarring stiffness most diamonds deliver.

Highlights
What makes this racket stand out
Diamond head with high balance — sweet spot sits high for overhead finishing, with little forgiveness on low mishits
Black EVA core paired with Soft Carbon face — softer than the standard Viper, with VIBRABSORB SYSTEM² damping that takes the edge off contact
365g (±10g) at 38mm thickness — heavy enough for stability on smashes, demanding enough that under-70kg players will tire by the third set

Our verdict
What the shape, core and construction tell us about how this racket is built to play.
The short version
The Technical Viper Soft 3.0 is the diamond for the left-side attacker who has been told their current racket is wrecking their elbow but doesn't want to drop down to a teardrop. It hits hard overhead and dampens the worst of the vibration, but it's still a 365g high-balance frame — anyone playing the right side, or anyone without clean technique, will get less out of it than they paid for.
Strengths
Left-side players who finish points with bandejas, víboras and smashes
Advanced attackers with elbow sensitivity who can't tolerate a full-stiff diamond like the standard Viper
Keep in mind
Beginners or right-side control players — the high balance and small sweet spot will punish inconsistent contact
How it's built to play
The Technical Viper Soft 3.0 sits in an interesting niche: a true diamond frame for attackers, but built with comfort layers most diamonds skip. Babolat has taken the aggressive geometry of the Viper line and softened the contact without softening the intent. The result is a racket that still rewards left-side specialists with overhead pop, but won't beat up the arm of a player coming back from epicondylitis the way a pure carbon-and-hard-EVA build would.
The face uses Carbon Twill 3K in a Soft Carbon construction — the 3K weave keeps the surface stiff enough to transfer energy on smashes, while the soft-carbon treatment dulls the high-frequency feedback that makes harder carbon faces uncomfortable on mishits. The Black EVA core is on the softer side for an attacking frame, which extends ball dwell slightly and absorbs vibration before it reaches the handle. Babolat backs this up with VIBRABSORB SYSTEM² Powered by SMAC: elastomer inserts placed in the heart and grip that bleed off vibration at contact, which matters because a 365g diamond hit off-centre is exactly the load pattern that triggers tennis elbow.
The Dynamic Stability System — a reinforced central bar in the heart — stiffens the frame's torsional response, so the head doesn't twist on off-axis impacts. That's the trade-off Babolat is managing here: soften the feel, but keep the frame from going floppy. The 3D SPIN+ textured face gives the kind of grip on the ball you need for víbora and chiquita variations from the back of the court.
On overheads, this plays like a diamond should — the high balance loads the head through the swing and the ball comes off hot. What stands out is what happens when you don't middle it: instead of the sharp sting most diamonds send up the arm, you get a duller, more contained feedback. It's still a diamond, so mishits lose noticeable pace, but the punishment is physical rather than neurological.
From the back of the court the softer core helps more than you'd expect for a head-heavy frame — there's enough dwell to shape a lob or roll a topspin lob over an aggressive net player. Defensive volleys on the right side are the weak spot: the balance is wrong for quick reaction blocks, and the small sweet spot means a right-side player will frame more balls than they'd like under pressure.
FAQ
How does the Technical Viper Soft 3.0 compare to the standard Technical Viper?
The Soft 3.0 uses a softer Black EVA core and the Soft Carbon face treatment, plus the VIBRABSORB SYSTEM² damping inserts. The standard Viper is stiffer and more explosive at contact, but transmits more vibration. Choose the Soft 3.0 if you want the diamond shape and attacking balance but have any elbow history; choose the standard Viper if you're young, strong, and chasing maximum pop.
Should I choose the Technical Viper Soft 3.0 or a teardrop like the Bullpadel Vertex 04?
Both are advanced attacking rackets, but the Vertex 04 is a teardrop with the sweet spot slightly lower — more forgiving on bandejas and easier to use from the back of the court. The Viper Soft 3.0 is a true diamond: higher sweet spot, more demanding, more overhead-specific. If you play left side and finish points above your head, the Viper. If you split duties or want one racket for both sides, the Vertex.
Is this racket actually safe for players with tennis elbow?
Safer than most diamonds, not safe in absolute terms. The softer core, Soft Carbon face and VIBRABSORB damping all lower the vibration profile, but it's still a 365g head-heavy frame — and that combination loads the elbow on every off-centre hit. If you're actively rehabbing, a round frame with a soft core would be a lower-risk choice. If you're managing chronic sensitivity and refuse to give up the diamond shape, this is one of the more arm-friendly options in the category.
Can a strong intermediate use the Technical Viper Soft 3.0?
Possibly, if the intermediate plays left side, has clean overhead technique and weighs over 75kg. The smaller sweet spot punishes inconsistent contact — if you frame more than one ball in five from mid-court, you'll lose more points to mishits than you gain on smashes. Most intermediates are better served by a teardrop until their consistency catches up.
What does Soft Carbon actually mean on court?
Soft Carbon is Babolat's way of using a Carbon Twill 3K weave with a finish that flexes microscopically more than standard 3K carbon. On court that means the contact feel is slightly less hard, less ringing through the frame on clean hits and less spiky on mishits. You still get the energy transfer of carbon — it's not a fiberglass face — but the surface treatment takes some of the brittleness out of the response.
