The Bullpadel Hack 04 Comfort is the comfort version of Paquito Navarro’s power diamond: the same diamond shape and balance of about 264 mm, but a Fibrix face that blends carbon and fiberglass, and a lower weight of 360–370 g. Bullpadel’s aim is to keep the Hack’s dynamic power with a softer, more forgiving feel for the arm.
The US listing is the 2026 racket, and it costs about $260. This review covers the build, the specs, how it should play, how it differs from the standard Hack 04 and who should buy it.

Our review of the Bullpadel Hack 04 Comfort
The Hack 04 Comfort is a power diamond with the edges softened. Its ratings tell the story: power 2.5 out of 5, against 4 for the standard Hack 04, and a feel rated intermediate rather than intermediate to hard. The weight is 360–370 g, about 5 g lighter at both ends of the range, and the Fibrix face replaces the stiffer TriCarbon 18K.
One rating stands out: Bullpadel still gives the stiffness a 4 out of 5, the same as the standard racket, and the control rating is only 2. That suggests the comfort comes from the softer face material and the lower weight, not from a soft frame, and that the racket is still a demanding diamond for players who miss the center.
We have not played it ourselves, so this is an assessment of Bullpadel’s spec sheet and ratings. On paper it suits an advanced player who likes the Hack’s shape but wants an easier ball exit and a lighter swing.
Pros
- Lighter than the standard Hack 04
- Fibrix face is softer than TriCarbon
- Aerodynamic channels and Tricore structure
- Ease Vibe and Vibradrive damping
Cons
- Control rated only 2 out of 5
- Stiffness still rated 4 out of 5
- Lower power than the standard Hack 04
- Premium US price
Who is the Bullpadel Hack 04 Comfort for?
The Hack 04 Comfort suits advanced attackers who want a diamond that is easier on the arm than the standard Hack, and players coming back from arm trouble who still want a head-heavy racket. It also suits players who find 365–375 g diamonds tiring.
Who the Bullpadel Hack 04 Comfort is not for
Skip it if you want a forgiving racket, because the control and sweet spot ratings are modest, or if you want maximum power, where the standard Hack 04 and the Xplo are stronger. Beginners should start with our beginner racket guide.
What to know before you buy the Bullpadel Hack 04 Comfort
Comfort versus standard versus Hybrid
The standard Hack 04 has a TriCarbon 18K face and a power rating of 4. The Comfort has a Fibrix face and a rating of 2.5, and the Hack 04 Hybrid is a hybrid shape with a lower balance and the highest control rating of the three.
Weight and balance
Bullpadel lists 360–370 g with a balance of about 264 mm and a 38 mm profile. The balance is the same as the standard racket, so the head-heavy feel remains.
A 2027 version already exists
Bullpadel’s own store lists a 2027 Hack 05 Comfort, so the Hack 04 Comfort is last season’s racket. A previous-season racket is usually the better value, but US prices depend on stock.
How the Bullpadel Hack 04 Comfort plays
Smashes and the vibora: A diamond with a balance of about 264 mm gives head weight, although the softer Fibrix face sends the ball out with less bite than the standard racket. Our guides to the kick smash and the vibora cover the technique.
Volleys: Lower weight helps reaction speed at the net, and the Tricore structure keeps the head stable.
Defense: Easier than on the standard Hack because of the weight and the softer face, but a diamond is still not a defensive racket.
Comfort: Ease Vibe and Vibradrive damping and the Fibrix face are the main comfort features.
Bullpadel Hack 04 Comfort vs the alternatives
Inside Bullpadel, the standard Hack 04 is the stiffer power version, the Hack 04 Hybrid is the control version, the Xplo Comfort is the comfort version of the Xplo and the Vertex 05 is the all-rounder. Outside Bullpadel, the Babolat Technical Viper Soft is another softer power diamond. Our best rackets for advanced players guide compares the wider field.
Is the Bullpadel Hack 04 Comfort worth it?
At about $260 from a third-party seller, the Hack 04 Comfort is expensive against Bullpadel’s own store price of about 190 euros for the 2026 racket. It is worth it for an advanced attacker who wants exactly this softer Hack, and poor value for anyone who would be happy with a cheaper diamond.
Conclusion
The Bullpadel Hack 04 Comfort is a lighter, softer-faced version of the Hack power diamond. Its strengths are weight, comfort features and aerodynamics. Its weaknesses are the control rating, a still-stiff frame and the US price.
Choose it if you like the Hack but want an easier ball exit. If you want more power, see the standard Hack 04, and browse our best padel rackets roundup for every level.
