Bullpadel Hack 04 Hybrid 2025

Technologies

Pros

• ✓TriCarbon 18K delivers a crisp, direct response on smash and vibora shots — the ball comes off the face fast with minimal dwell time; the 3D Grain surface bites into cut shots noticeably, especially on sliced bandejas and topspin viboras that dive down; Ease Vibe soaks up up to 49% of impact vibration, letting you grind through long matches on a firm Multieva core without hammering your elbow; the 38mm profile with Total Channel and Air React Channel adds stiffness without stiffening you up — the racket holds its line on blocked volleys against pace; and the Custom Weight system plus stock Hesacore let you dial in the head-heavy balance and grip feel to your swing without any DIY tweaks

Cons

• ✗Ball exit is short — in deep defense, hitting a lob cross-court off the back wall, you have to muscle it because the racket won't add those extra metres for you; the sweet spot is small and sits high on the face, so a low or off-centre wall exit comes back dead; the head-heavy balance demands early prep on fast wall exits — arrive late and the head gets heavy while the ball comes up short; and 365-375g on a firm Multieva core is a demanding ask on wrist and shoulder — without solid smash technique it can start causing discomfort

The Bullpadel Hack 04 Hybrid 2025 is designed for competition or pro-level players who prioritise performance and precision over comfort. Its teardrop shape shifts the sweet spot slightly upwards, striking a balance between control and power. The high balance adds weight to the swing and pushes the racket toward an offensive profile. Its 365-375g weight range places it in the medium-weight group, the most common among amateur players.

Bullpadel Hack 04 Hybrid 2025 Review: Paquito Navarro's Hybrid Teardrop Racket

Some rackets are defined by their spec sheet, others by who swings them. The Bullpadel Hack 04 Hybrid 2025 is firmly the latter: it's Paquito Navarro's official 2025 racket on Premier Padel, built with a TriCarbon 18K face, Multieva core, 38mm profile and 365-375g spread across a 529cm² hitting surface. Aggressive 3D Grain texture, stock Hesacore and a head-heavy balance round out a padel racket that doesn't hide what it's built for.

Why is it called "Hybrid" if the shape is a teardrop?

The shape is teardrop, but one that leans towards round. Bullpadel positions this profile as a middle ground: it borrows some of the control and forgiveness of round rackets while keeping the extra acceleration that comes from having mass above the geometric centre.

On court that translates into something very specific: the sweet spot isn't dead centre, it sits a touch higher. Hit there and the racket answers with a crisp, fast ball exit. Hit below it and the ball feels flat and lifeless.

That shifted sweet spot is what makes this a demanding racket rather than an easy one. It's worth knowing before you buy it.

TriCarbon 18K over Multieva: what each layer actually does

TriCarbon 18K is a dense-weave carbon fibre face. Its main effect is surface rigidity: the face barely flexes on contact, so the ball spends less time on the string bed and exits sooner. That's what gives you the "crisp" feel and the immediate response on smashes.

The Multieva core blends different foam densities within a single piece. The impact zone plays notably firm, though the overall feel doesn't reach the total stiffness of a uniform high-density EVA core.

Built on top of that are the Tricore and Carbon Tube, which reinforce the frame's internal structure, plus Vibradrive and Ease Vibe, which together absorb up to 49% of impact vibration. Without that filtering, an 18K carbon face over a firm core would be tough to handle for a full match.

The Total Channel and Air React Channel work the frame's channel geometry, adding torsional stiffness without piling on weight. Smart Holes tweaks the perforation pattern to fine-tune response by zone.

How does it play, shot by shot?

Smash and flat overheads. This is where the racket shows the least hesitation. The combination of 18K carbon, a firm core and high mass accelerates the head fast and sends back a taut, penetrating ball. The kick comes through with height without you having to overswing.

Bandeja and vibora. The 3D Grain is the difference-maker here. The texture genuinely bites on cut shots — the bandeja stays low after the bounce and the topspin vibora drops with real curve. This is one of those rackets that lets you feel the spin in your hand.

Volleys. The 38mm frame with its reinforcement channels keeps the face stable when blocking. Against pace, the racket doesn't twist in your hand, letting you block volleys right at your opponent's feet.

Wall exits and defense. This is where the trade-off shows up. The ball won't exit on its own — defend with a passive arm or arrive just late to a fast wall ball and the lob comes up short. You have to actively drive the shot yourself.

What level of player is this Bullpadel racket for?

Straight answer: this is a competition racket. It demands a well-grooved swing, a wrist used to handling 365-375 grams, and the ability to hit the sweet spot consistently. An intermediate player who hasn't yet found that sweet spot reliably will end up working harder than the racket gives back, especially on defense.

Who it suits best:

1. Net players who smash regularly and like to close out points with vibora or overhead smashes.
2. Players with an already-built wrist technique, able to generate pace themselves rather than relying on the racket to do it.
3. Players who prefer a crisp, predictable response over a springy, forgiving racket.
4. Ideal doubles partner: someone with a more forgiving racket and better natural ball exit, to cover defense while you dominate the net.

The Custom Weight system helps you personalise the weight distribution — if the head-heavy balance feels too aggressive on defense, this is how you adjust it without altering the original build.

Verdict: power on tap, not power handed to you

The Bullpadel Hack 04 Hybrid 2025 is a racket with character, not one built for comfort. It gives you a crisp ball exit and serious spin potential, but it demands you put in the groundwork first: early preparation, centred contact and the physicality to swing 375 grams for an hour and a half.

Ease Vibe and Hesacore do a lot of the heavy lifting to make that demand sustainable, which is why the package holds up on tour. But neither turns that small sweet spot into a big one.

If you're after a racket that bails you out in defense, this isn't it. If you want one that responds exactly the same every time you strike it well and lets you sign your name on the spin, this Bullpadel delivers.
