Q36.5 Gregarius Signature Sleeveless Jersey Info
The Q36.5 Gregarius Signature Sleeveless Jersey is a sleeveless cycling jersey designed for climates with extreme heat. Q36.5 makes it in Italy, and the company lists the weight at 100 g in a size M, so it is a very light layer for the hottest days of the riding season. The jersey carries the Radar logo that Q36.5 first launched with its 2025 Pro Cycling Team kit. Q36.5 describes the radar as a symbol of focus and navigation under difficult conditions.
3D fabric across the front
The front of the jersey uses an almost imperceptible three-dimensional fabric. Q36.5 says the structure improves the wicking process and creates a natural air barrier between your skin and the jersey, which is meant to improve thermoregulation in extreme heat. The structure is subtle enough that you are unlikely to feel it as texture. The benefit is airflow against the skin on long, hot climbs.
Honeycomb mesh back
The back panel uses a honeycomb mesh pattern. Q36.5 engineered it to prevent moisture build-up by encouraging a push-pull effect, which moves sweat to the outer layer of the fabric where it can evaporate quickly. In a forward riding position, your back is the area most exposed to your own heat, so this panel does a lot of the work when the temperature rises.
Materials and temperature range
The fabric is 82 percent polyester, 14 percent elastane and 4 percent polyamide, according to the Gravel Grey listing on Q36.5's site. The company lists a body temperature stability guarantee of 64°F. For riders who overheat in a standard short sleeve jersey, removing the sleeves entirely is the simplest way to stay cooler, and this jersey is built around that idea.
Fit and sizing
The jersey is available in sizes XXS through XXXL. Our size chart on this page lists chest, waist, height and weight ranges for each size. Check it before ordering, since a performance jersey like this one is cut to fit close to the body.
The Q36.5 Gregarius Signature Sleeveless Jersey is a good choice for riders who want a minimal, well-ventilated Q36.5 jersey for summer road rides and long days in extreme heat.
The RA Perspective
The Gregarius Signature Sleeveless is a very specific jersey, and it does that one job well. At 100 g in a medium, it is among the lightest jerseys you can wear, and it is meant for the days when even a short sleeve feels like too much.
The 3D fabric across the front and the honeycomb mesh back are the two details that matter. Q36.5 designed the front to hold a layer of air against your skin, and the back to move sweat outward so it evaporates. In practice, that gives you ventilation on both sides of your torso when you are working hard on a climb in midsummer.
The tradeoff is that you give up the sun coverage and the slight protection of sleeves. If you are riding long days in strong sun, you will want sunscreen on your shoulders, and the jersey is no use on a cool morning. At $190, it is also a premium price for a piece that you will wear on a narrow range of days.
We would pick this one for summer climbs, gran fondos in hot climates and any ride where overheating is the main concern.
