Highlights
What makes this racket stand out
TriCarbon 18K tridirectional face delivers fast energy return on overheads without adding frame weight
Total Channel runs the hollow aerodynamic groove around the entire perimeter — Bullpadel claim 17% better aerodynamics and 7% more stability versus a standard frame
Vibradrive and Hesacore grip work together to pull vibration out of the handle — meaningful on a high-balance diamond that would otherwise send every off-centre hit straight to your elbow

Our verdict
What the shape, core and construction tell us about how this racket is built to play.
The short version
The Hack 04 Chile is a precision instrument for the left-side attacker who already hits hard and wants a racket that channels that aggression rather than taming it. The TriCarbon face and Total Channel frame make it genuinely quicker through the air than most diamonds at this price, and the Smart Holes configuration sharpens the overhead response to a degree you can feel from the first session. The honest limitation: anyone who isn't generating consistent pace from the left will find this racket working against them — and anyone with elbow history should look elsewhere in the Hack range, regardless of how appealing the Vibradrive sounds on paper.
Strengths
Left-side attackers who generate high swing speed and want to convert that pace into decisive overhead smashes and bandejas
Advanced club or competitive players with consistent technique who need a racket that rewards aggressive play rather than compensating for inconsistency
Keep in mind
Players with elbow or shoulder sensitivity — diamond shape, high balance, stiff carbon face, and EVA core combine four high-risk factors; the Vibradrive helps at the handle but cannot offset the impact forces generated closer to the face
How it's built to play
The Hack 04 Chile is a limited-edition variant of Bullpadel's flagship attacking line, created to mark the Premier Padel Santiago tournament. Strip away the Andean condor graphics and what you have is a full-blooded left-side weapon: diamond shape, high balance, TriCarbon face, MultiEVA core, and a frame channelled to slice through the air faster than a standard construction. This is not a racket that hides what it is. Every design decision points toward one thing — finishing points from the left with the least resistance possible.
The face is TriCarbon 18K, Bullpadel's tridirectional 18,000-filament carbon weave. The three-direction architecture gives the face a controlled elasticity that standard biaxial carbon doesn't produce — the surface snaps back faster after contact, which translates to better energy return on hard, fast balls like overhead smashes and counter-attacks. Paired with Smart Holes, which removes perforations from the central face area to increase rigidity at the sweet spot, the hitting zone feels tight and direct — you get exactly the power your swing generates, with no spring assist from the face itself. The MultiEVA core runs two densities: a denser outer layer that reacts to fast incoming balls and returns power, and a softer inner layer that cushions slower shots and adds some control. It's a smart construction for an attacking racket that still needs to handle reset volleys and defensive touch shots. The 100% CarbonTube frame wraps the perimeter in pure bidirectional carbon — this is what gives the Hack 04 its torsional rigidity under high-impact conditions. Total Channel extends the aerodynamic hollow groove around the entire frame perimeter, not just the throat; the result is a measurably faster swing arc, which matters most when generating racket head speed on overheads. The Curv:aktiv geometry twists the frame's side walls to resist torsion on off-centre hits — at this balance point, that stability is doing real work.
At the net and in attacking positions, the Hack 04 Chile does what its specs promise: overhead smashes land with pace and direction, the 3D Grain surface texture bites into the ball enough to add spin on bandejas, and the tight frame response makes placement feel intentional rather than approximate. The Total Channel's aerodynamic advantage is most noticeable on full swing shots — the racket accelerates through the hitting arc with less drag than a conventional diamond frame, which helps players who generate their power through swing speed rather than body mass. Where it gets honest is in slower exchanges and defensive stretches. The MultiEVA core's inner layer softens the blow, but this is still a high-balance EVA diamond — resets and drops from mid-court require deliberate deceleration. Players who drift out of position will find the small sweet spot punishing. The Vibradrive rubber handle assembly and Hesacore octagonal grip absorb a meaningful portion of the vibration that this type of construction normally sends up the arm, but they work best on clean contact. On repeated mishits — the kind that come with fatigue or opponents pushing you wide — the arm will still feel it.
FAQ
How does the Hack 04 Chile compare to the Hack 04 Premier?
Both share the same Hack 04 platform — diamond shape, high balance, TriCarbon face, MultiEVA core — so the core playing experience is very close. The Chile edition is a limited run tied to the Premier Padel Santiago tournament and typically sits at a lower price point than the Premier variant. If the specs are identical in your size and the Chile is available, the choice comes down to budget and aesthetics rather than any meaningful performance difference.
Should I choose the Hack 04 Chile or the Bullpadel Vertex series?
Both are high-balance diamond rackets built for attackers, but the Hack line (historically associated with Paquito Navarro) is engineered specifically around swing speed and aerodynamic efficiency — Total Channel is the clearest expression of that. The Vertex series (associated with Juan Tello) uses Air Power and Curv:aktiv to prioritise all-court versatility alongside power. If you play almost exclusively on the left and want maximum overhead pace, the Hack 04 Chile is the sharper tool. If you move between positions or want a diamond that still handles defensive stretches comfortably, the Vertex is the more forgiving choice.
Is the Hack 04 Chile 2025 suitable for players with elbow problems?
Not recommended. The combination of diamond shape, high balance, stiff TriCarbon carbon face, and EVA core represents four of the five high-risk factors for lateral epicondylitis. Bullpadel has added Vibradrive (a rubber handle assembly that absorbs handle-end vibration) and the Hesacore grip, which genuinely reduce transmitted shock — but these work at the handle, not at the face where the initial impact force is generated. Players returning from elbow or shoulder injuries should consider a round or teardrop shape with a softer foam core and fiberglass face instead.
What does the Custom Weight system on the Hack 04 Chile actually do?
Custom Weight lets you insert aluminium adhesive plates (up to three, each 3g) into compartments in the frame's Metalshield protector. Adding plates toward the head increases balance point and adds momentum to overhead smashes. Adding them lower, or leaving them out, keeps the racket more manoeuvrable. For most left-side attackers, adding weight toward the head makes sense — but if you find the stock high balance tiring over long matches, leaving the plates out gives you a slightly faster-handling version of the same racket.
What is Total Channel and does it make a noticeable difference on court?
Total Channel extends Bullpadel's hollow aerodynamic groove around the entire frame perimeter rather than just through the throat arms. The principle is drag reduction: less air resistance during the swing arc means the racket head accelerates faster with the same effort. Bullpadel cite a 17% aerodynamic improvement and 7% more stability compared to a non-channelled frame. On court, the effect is most perceptible on full-swing overhead shots — the racket feels like it builds speed through the swing rather than requiring you to force it. On compact volleys and touch shots, the difference versus a standard frame is minimal.
