Bullpadel Hack 05 Comfort 27

The Bullpadel Hack 05 Comfort 27 is Paquito Navarro's diamond with the carbon face swapped for Fibrix. The published specs show that face swap as the one clear difference from the standard Hack 05. Shops list it for 2027, at professional level, with the same attacking skeleton as the rest of the Hack 05 family. Everything below comes from the specs and retailer listings, because no independent court test of this racket has been published yet.

Fibrix instead of 18K carbon: the one swap that defines the Comfort

Put this next to the Bullpadel Hack 05 27 and the frame of the story is identical. Same diamond shape, same MultiEVA core, same 38 mm thickness, same Paquito Navarro name on the page. The difference is the face. The standard Hack 05 uses 18K carbon. The Comfort uses Fibrix.

Bullpadel describes Fibrix as a mix of fibreglass and carbon. Treat that as the brand's own claim, not a lab result, but the logic is familiar. Fibreglass flexes more than carbon. More flex means the ball stays on the face a touch longer and the impact feels less sharp. That is exactly what the comfort meter shows: Low on the standard Hack 05, Medium here. On the meters, that softer touch is the main change this version brings.

360 to 370 g, diamond, head-heavy: the attacking skeleton that stayed

Do not let the word Comfort fool you into thinking this is a light, easy racket. Retailers list it at 360 to 370 g, diamond shaped, with a 522 cm2 head and a rough 3D surface for grip on the ball. The balance is listed as High, Medium, which points to a head-heavy racket with some room to adjust. An exact balance in millimetres is not published, and neither is the handle specification.

A diamond at that weight wants one thing: to end points. Overheads, bandejas with intent, volleys punched through the court. The rough surface should help you add slice and kick to those shots. Retailers also list a Custom Weight system, so you can shift the balance or total weight with small weights rather than accepting the factory setup. Shops describe the player profile as offensive. The specs agree.

Comfort on the label, Medium on the meter: what the soft face buys you

Medium comfort, not high. That matters. The MultiEVA core and the Fibrix face both soften the blow, but the heavy build and the head-heavy balance push comfort back down. You get a friendlier Hack, not an arm-friendly racket in the round, head-light sense.

Retailers list EasyVibe and Vibradrive as the vibration damping on this model, and Bullpadel's own page says these improve the feel at impact. Again, those are claims, not measurements. If your elbow already complains, the soft face helps at the margins, but 370 g hanging high in the head is still a load. A lighter, more even racket would do more for a sore arm than this one.

Low control, Low sweet spot: what the diamond still asks of your timing

Here is the bill for all that power. Control rates Low, and the sweet spot rates Low too. That is not a flaw in this particular racket. It is what a diamond shape does. The mass sits high, the forgiving area is small, and balls struck away from the centre lose pace and direction quickly.

In practice that means your defensive lobs and off-balance blocks need clean technique. Late contact gets punished. If you generate your own power and place the ball well, you will not notice it as a problem. If you are still grooving your swing, you will. The meter does not care how the marketing reads.

Hack 05 Comfort 27 versus Hack 03 Comfort: a changed label, not a rebuild

Compared with the HACK 03 COMFORT, the published specs are nearly a copy. Same MultiEVA core, same Fibrix face, same diamond shape, same 360 to 370 g. The only recorded difference is the balance label, which moved from High to High, Medium. A changed label is a changed label, not a measured change in how the racket plays. Several specs of the older model were never published, so a fuller comparison is not possible.

If you already own the Hack 03 Comfort, there is no spec-based reason here to switch. If you are choosing between the two, you are choosing between two very similar rackets on paper.

Custom Weight, EasyVibe and no court test yet: what you cannot check

Two honest gaps remain. First, nobody independent has published a court test of this racket. Everything you have read comes from the spec sheet, retailer listings and Bullpadel's own product page. Reviewers may confirm the softer feel. Or they may find the diamond backbone takes over on court. You cannot know yet.

Second, some listings are thinner than others. The balance in millimetres is unverified, and the handle spec is missing entirely. If those details matter to you, check them in a shop before buying. On paper, though, the picture is consistent: a heavy, head-heavy diamond for attackers, with a fibreglass-rich face taking the sting out of it. Not a radical idea, but a clear one.
