Gregarius Pro Signature Bib Shorts Black
Totally redesigned from the ground up for 2025 with 100% proprietary components, the Q36.5 Gregarius Pro Signature Bib Shorts for Men have been engineered to provide the rider with the most free, unrestricted, and “not-even-there” on-the-bike feeling, without any compromise to our signature comfort and ergogenic support. This uniquely unrestricted feeling of the Gregarius Pro is the result of system which fuses a new ergogenic pattern (four different fabrics, minimal stitching) with our revolutionary adaptive chamois pad. The Q LAB Air Chamois employs single layer cover fabric without lamination or foam for rapid drying and breathability during hot conditions while the C-shaped foam pad underneath is inserted directly into the pattern of the shorts, creating a single plane from straps to groin. This design offers noticeably superior stability and comfort for the rider. Even during the hardest moments of the climb, you will need to look down at your legs to remind yourself that you are even wearing anything!

Great quality and comfort. My only wish is that they were a little longer, as I'm a 196cm tall and have long legs.

An excellent product. Extremely high quality and well designed. The chamois is the best I have ever used, and I have tried many different, high end brands. The Q36.5 logos on this model look great too.

The Q36.5 Base Layer 1 represents our technologically extreme vision of the traditional seamless base layer that provides optimal moisture management thanks to our use of the cutting-edge Karl Mayer Seamless knitting machines. The seamless design uses multiple integrated yarn structures with varying densities to pull sweat away from the skin and move it to an outer layer where it can evaporate.
080.1.S-M
The traditional cotton cycling cap has been fine-tuned by Q36.5 through the use of a knitted lightweight polyester and the addition of two polyester mesh inserts on the sides of the central panel which offer a closer fit as well as ventilation. A polyamide sweatband promises a zero- irritation interface with the skin and efficiently wicks perspiration.

Q LAB Air Chamois
Q LAB Air Chamois is a proprietary development that will revolutionize your on-the-bike comfort thanks to the use of two separate layers that move independently to adapt to a rider’s position. This means your chamois always offers total protection no matter your position on the bike. The top layer and open-air construction reduce friction typically caused by stitching and material overlap.
100% Proprietary Components
The Gregarius Pro Bib Shorts are made from 100% internally developed components that cannot be found on any other bib shorts on the market. This guarantees a uniquely high performance product in which every part has been designed in absolute harmony with all other parts of the bib shorts.
Ergogenic Minimalist Pattern
The Gregarius Pro Bibs are constructed using the least amount of stitching possible for greatest comfort, combined with proprietary design features and fabrics to provide our signature feeling of muscular support.
Lumbar Support System
Made from a proprietary high density woven fabric, this panel provides additional compression to create a zone of support for the lumbar and gluteal musculature. The improved stability results in increased power output.
Raw Cut
The raw-cut leg hems provide support without squeezing since they don’t employ uncomfortable elastic and silicon strips. They stay in place with no pressure points no matter the intensity of the effort.
