Weighing 290 grams in size L, the Gonso is not one of the lightest models in the test. However, its weight is due to the comparatively bulky thermal material. On the other hand, it provides the jersey A warm, comfortable feeling straight away. The fit is comfortable and, with sizes ranging from XS to 3XL, offers plenty of room even for riders with a less race-oriented build.
When it comes to weather protection, the clear limitations of the Gonso concept become apparent. The Stivio Jersey Therm M does not have a wind- or water-repellent membrane and is awarded a score of 4.0 in this category. The fabric therefore offers significantly less protection against wind and wet conditions than most of its competitors in the test. A wind vest or a lightweight rain jacket should be packed in case of changeable weather.
This design need not be a disadvantage if the intended use is right. Without a membrane, moisture can escape from the inside more easily than with heavily insulating materials. This is pleasant on dry autumn and spring days. On longer descents, in open winds or in the rain, however, the Gonso is not suitable as a standalone outer layer. This is precisely where many weather-resistant jerseys with windproof front panels or water-repellent outer fabrics come into their own.
The score of 1.6 for fit and comfort confirms our practical impressions. The Gonso isn’t extremely tight-fitting, but rather comfortable and allows for freedom of movement. This sets it apart from highly race-oriented long-sleeved jerseys, whose cut is designed for a very low road cycling position. For ambitious cyclists looking for a less restrictive top, this is an advantage.
The concealed zip improves comfort around the neck and makes it easier to regulate body temperature. Reflective material also enhances visibility in low light. Overall, the design remains simple, which is reflected in the sub-score of 3.0. Anyone expecting a particularly large number of pockets, silicone cuffs or comprehensive weather protection will find more functionally advanced alternatives in the comparison.
At 139.95 euros, the Gonso is one of the more affordable models in the test. Compared with the other models, it is cheaper than many weather-resistant jerseys featuring a membrane, but it also falls short in terms of protection against wind and rain. Its overall score of 2.8 places the model towards the bottom of the test field.
For riders who are deliberately not looking for a heavily insulated all-weather jersey, the value for money is still reasonable. The Stivio Jersey Therm M is available in three colours and is ideal as a warm, comfortable long-sleeved jersey for dry training rides. Gonso describes the Stivio range as a close-fitting road cycling jersey with a focus on freedom of movement and moisture management.

The Gonso Stivio Jersey Therm M impresses with its soft, cosy fabric and a comfortable fit. Riders who aren’t looking for a tight-fitting race jersey will particularly benefit from its relaxed fit. When it comes to weather protection, however, Gonso has its limitations: Without a wind- or water-repellent membrane, the jersey offers significantly less protection than many competitors in rain, wind and on long descents. On the other hand, the price remains comparatively low at €139.95. A good choice for cool, dry training days, and can also be easily combined with a wind vest or jacket.
