Q36.5 Gregarius Pro Bib Shorts Info
The Q36.5 Gregarius Pro Bib Shorts are Q36.5's summer-weight performance bib shorts, redesigned for 2025 and made in Italy. Q36.5 produces them from start to finish in Italy, within a short radius of its Bolzano headquarters. The brand's focus here is a pattern that uses as little stitching as possible, with four different fabrics placed where the body needs support, stretch or airflow.
Q36.5 calls the construction its Ergogenic Minimalist Pattern. The fabric blend is 71% polyamide, 26% elastane and 3% silver. Rather than cutting the short from a single material, the pattern combines four fabrics with minimal seams, which is meant to cut down on pressure points and bulk in the saddle. The leg hems are raw-cut with no silicone grippers, and Q36.5 says they provide support without squeezing. A lumbar panel in a proprietary high density woven fabric adds compression across the lower back and glutes.
The chamois is the Q LAB Air. It uses two separate layers that move independently to adapt to a rider's position, with an open-air construction on the top layer. The cover is a single layer of fabric without lamination or foam, and a C-shaped foam pad sits inside the pattern. Q36.5 designed this for fast drying and breathability in heat, which is where these shorts are aimed. The brand lists a Body Temperature Stability Guarantee of +64°F, so expect these to be best suited to warm and hot days rather than cold-weather rides.
The Gregarius Pro Bib Shorts are available in six colors: White, Black, Nautica Blue, Drab Green, Check Grey and Gravel Grey. Sizes run from XS to XXXL, and Q36.5 provides a size guide with chest, waist, height and weight ranges. Check your measurements against it before ordering. This short suits riders who want a lightweight, breathable, Italian-made bib for long summer rides, training, and racing, with a chamois designed for hot weather.
The RA Perspective
The Gregarius Pro is aimed at hot-weather riding. Q36.5 builds it around a minimalist pattern with four fabrics and as few seams as possible, plus a Q LAB Air chamois with a single-layer cover and a C-shaped foam pad. If you ride mostly in summer heat, those are the details that matter.
We have not put long hours in this redesigned version yet, so we cannot speak to chamois comfort past a few hours or how it compares to the Dottore line. Q36.5 redesigned the short for 2025, which also means reviews of earlier versions may not describe this one.
The raw-cut hems use no grippers. That keeps the legs free of squeezing, but some riders prefer a gripper for a locked-in feel, and fit differs from person to person. Check the size guide against your chest, waist and height, and if you are between sizes, call the shop.
At $290 this is a premium bib. It is made in Italy, it has a purpose-built summer chamois and it has the lumbar support panel, which is the sort of detail riders either notice or do not.
We would reach for it on warm group rides, long weekend rides and race days when staying cool is the priority.
