Rebelhorn Jax motorcycle jacket put to the test

Rebelhorn comes from Poland and, according to its own information, has been developing motorcycle apparel for more than 20 years, designed, tested and continuously refined in the heart of Europe. So there's no freshly hatched start-up behind the brand quickly ironing a martial logo onto some product imported from overseas, but rather a manufacturer with a now broad range of jackets, pants, gloves, boots and other protective gear. Modern materials, high protection standards and fair prices form the basis of the range. What matters, though, isn't what's stated on the manufacturer's website, but what actually reaches the rider on the road. That's why we don't just look at certifications and technical data, but above all at construction quality, fit, wearing comfort and the impression it makes in the saddle.

At first glance, the Rebelhorn Jax looks like a sportily cut summer jacket whose large mesh zones aren't quite as demonstratively displayed as on the even more radical Scandal 3 (LINK TO 1000PS REPORT). The three-dimensionally structured 3D Matrix Mesh dominates the chest, back and sleeves, while 450D polyester and ripstop reinforcements give the critical areas more substance. The red colour variant emphasises these material changes particularly clearly; black, grey and green appear more restrained. The shortened front section and the longer back are aimed at a slightly forward-leaning seating position, but work just as well visually and ergonomically on naked bikes and upright-riding all-rounders. The collar and cuff finishes are softly bound, the zippers run cleanly and the workmanship leaves a generally coherent impression.

The scale also delivers an interesting surprise. The outer jacket in size M, including shoulder and elbow protectors but without the Humax inner jacket and back protector, weighs 1,555 grams. That makes it even 95 grams lighter than the previously weighed Scandal 3 in the same size and configuration. The removable inner jacket adds 365 grams, the separately weighed back protector another 495 grams. Fully assembled, the package comes to 2,415 grams. That's not lightweight construction, but it distributes on the body better than the raw number suggests. The Defender gloves, alongside this, feel noticeably beefier than the Core, without unpacking the touring-armour look via oversized hard shells or a long gauntlet.

For the Jax, Rebelhorn combines several polyester constructions, each taking on a different task. 450D polyester forms the sturdy base, ripstop reinforces the more stressed zones, while Steel Mesh and 3D Matrix Mesh handle airflow. With the three-dimensional mesh, the fabric doesn't lie completely flat against the underlying clothing, but instead creates small air channels through its spatial structure while retaining more shape stability than an especially soft mesh material. The Jax uses this breathable fabric so generously on the chest, back and sleeves that, without the inner jacket, it clearly passes as a fully-fledged summer jacket.

Particularly well done is how unobtrusively the mounts for the inner jacket are integrated into the outer construction. If the Humax layer stays at home, neither coarse fastening elements nor stubborn zipper edges sit directly against skin or base layers. Even thin civilian clothing isn't tormented by internal zip sliders or hard hook-and-loop patches.

Two side zip pockets hold keys, wallet or smartphone, while the waterproof inner pocket protects more sensitive small items. The short 8VST zipper connects the jacket to compatible motorcycle pants and reduces riding up at the back, but it doesn't replace a full circumferential connecting zipper of a sports suit. Reflective inserts are distributed across the front, sleeves and back, without turning the jacket into a hi-vis vest in daylight. Also practical are the easy-to-grip zipper extensions, which offer enough purchase even with gloves on. The zippers at the cuff ends create space for different glove gauntlets, while the extended back covers the kidneys even when the rider slides further forward.

The removable Humax inner jacket is the decisive difference to the Scandal 3 and significantly extends the Jax's range of use. Rebelhorn states a water column of 10,000 millimetres and breathability of 10,000 g/m\u00b2 per 24 hours. The membrane sits under the outer jacket and keeps wind and rain away from the body, but it doesn't prevent the mesh from soaking through during prolonged rain. This doesn't turn the Jax into a laminated all-season jacket, but it does make it a versatile summer jacket for cool mornings, commuting routes and changeable conditions.

Practical is the inner jacket's own front zipper. This way the membrane can stay closed while the outer zipper is opened slightly for ventilation in slow city traffic. Conversely, the membrane can also be opened without removing it. As a casual leisure jacket, though, it's barely usable: the sleeves are deliberately somewhat shorter and the cut is clearly designed for interaction with the outer jacket.

Installation is straightforward. Two smooth-running zippers as well as a loop at the collar and two each at the cuff ends connect the two jackets within a few minutes. This works easiest with the jacket taken off, since the four wrist loops otherwise require some patience. After that, the membrane stays reliably in place, doesn't twist and doesn't creep up the sleeves when putting the jacket on. Only on sweaty skin does getting in require a bit more effort. The soft finishes at collar and sleeves, as well as the unobtrusive zippers, show that Rebelhorn has also cleanly solved the unspectacular everyday details.

The Rebelhorn Jax is certified as a motorcycle jacket in protection class AA and comes equipped with Level 2 protectors at the shoulders and elbows. The position of the elbow protectors can be adjusted so they don't end up above or below the joint on arms of different lengths. This is especially important with a regular fit, because the cut offers more freedom of movement than a body-hugging leather jacket. Ripstop reinforcements are meant to support the outer material in exposed zones, while reflective inserts improve visibility in poor lighting conditions. The AA rating assesses the jacket as a complete garment, while Level 2 describes the damping performance of the individual protectors. A high number on the protector therefore replaces neither abrasion-resistant material nor clean seams and correct positioning on the body.

At 495 grams, the back protector adds almost half a kilogram, making itself felt more strongly than the relatively light Humax inner jacket. Fully equipped, the Jax climbs from 1,555 to 2,415 grams, with the back protector also covering part of the large-area ventilation. This isn't a peculiarity of Rebelhorn's construction, but the unavoidable consequence of a large protective component sitting between the back and the mesh. In return, the spine gets considerably more sensible protection than a thin foam pad would provide. When trying it on, you should therefore always use the configuration you'll actually ride in. A jacket that fits loosely without a back protector can suddenly feel noticeably more compact with membrane and protector installed.

On our tester, 1.75 metres tall and weighing 70 kilograms, the Jax in size M fit excellently. Without the inner jacket it sits comfortably loose, without flapping unnecessarily on the arms or torso. With the Humax layer installed, the material moves noticeably closer to the body, but remains far from feeling restrictive. Freedom of movement when reaching for the handlebars is maintained, the shoulder and elbow protectors follow the movements, and the short front doesn't create an annoying bulge of material in the seated position.

The relatively short sleeves of the inner jacket stand out when first trying it on, but they make sense in combination with the outer shell. If the membrane extended far into the outer cuffs, two layers of material, several seams and the glove gauntlet would have to coexist in a tight space there. So the inner layer ends a bit earlier and prevents a thick bulge of fabric at the wrist. Riders with very long arms should still check this area carefully. The outer sleeves themselves fit cleanly in size M, and the zippers at the cuff allow the opening to be adjusted for different gloves. The regular fit thus works for sporty naked bikes as well as for more upright all-rounders, without visibly committing to one particular category of motorcycle.

Without the inner jacket, the Rebelhorn Jax comes surprisingly close to the Scandal 3 in terms of airflow. The headwind hits the chest and arms across a large area, flows through the jacket and can exit again at the back. With its extremely high Steel Mesh content, the Scandal 3 remains the more radical heat specialist, but the gap turns out to be considerably smaller than the Jax's additional weather equipment initially suggests. Particularly convincing is that the internal fastening zippers disappear completely from perception when the membrane is removed, meaning the summer base function is uncompromisingly present.

With the Humax inner jacket installed, the character changes markedly as expected. The immediate airflow disappears, the jacket sits more compactly on the torso and the headwind is kept away from the body. Precisely because of this, its range of use extends further into cool mornings, shaded mountain passages and changeable weather, without needing to fit a separate windbreaker as well. At the same time, total weight rises above 2.4 kilograms and the openness that's so pleasant in heat is largely lost. So the Jax can't be maximally ventilated and fully wind-protected at the same time; it merely enables a quick switch between the two states. What matters is that this conversion works simply enough not to merely exist theoretically in the equipment chapter.

The Rebelhorn Defender are short touring gloves positioning themselves above the especially light Core. The difference becomes clear as soon as you touch them: 52 percent goat leather, TPU elements, Impacton damping and a Superfabric panel on the palm bring more material and a noticeably firmer structure into play. At the same time, the gauntlet stays short enough to fit under or over the Jax's cuff finish, without turning getting into a textile combo into a wrestling match. Perforated leather and nylon areas are meant to reduce heat build-up, while the three-dimensional 3DErgoGrip construction pre-shapes the fingers into a natural grip position. At 188 grams for the test pair in size M, the Defender comes in 63 grams heavier than the previously weighed Core gloves, but doesn't feel bulky or overloaded on the handlebars.

The hard TPU knuckle protector sits over an energy-absorbing Impacton layer, while the same viscoelastic material also supports further areas of the back of the hand and the palm. On the inside of the hand, Rebelhorn adds an abrasion- and cut-resistant Superfabric panel. Certification to EN 13594:2015 Level 1 KP confirms tested knuckle protection and a defined structural resistance, but doesn't turn the short touring glove into a race track glove. For everyday use, country roads and touring, the protection concept is comprehensibly built up; anyone demanding maximum reserves, a long gauntlet and Level 2 needs to choose a considerably more substantial category. The integrated visor wiper helps in the rain, but replaces a waterproof construction just as little as a windscreen wiper replaces the open roof of a convertible.

When it comes to fit, the positive picture of the Core gloves repeats itself. The test rider has relatively large palms but comparatively short fingers, which is why size M pinches at the palm with many manufacturers, while size L offers enough width but leaves excess material at the fingertips. The Defender fits cleanly over the palm in M, without becoming too long at the fingers. Particularly helpful is the strong pull tab, allowing the glove to be pulled on in a controlled way from behind, rather than tugging laboriously at individual fingers and seams. The firmer leather needs a bit more effort than the light Core, but afterwards sits snugly and with few wrinkles around the hand.

The plastic protectors sit close to the knuckles, but caused neither pressure points nor annoying friction in the test. When closing the fist, the pre-shaped construction follows the natural movement, allowing precise operation of throttle, clutch and brake. Compared directly to the Core, the Defender feels less airy and playful, but more substantial, robust and better supported. The ClearVision wiper on the left hand can be quickly swept over the visor when raindrops or spray reduce visibility. According to the manufacturer, the Clarino panels enable touchscreen operation, whose reliability naturally also depends on the display, screen protector and moisture.
