Bib Shorts Guide

The ultimate ultralight solution

Newly re-engineered for 2026, the Dottore Pro Clima bib shorts push our expertise in high density weaving to the limit, creating a pair of bib shorts that has a truly open and breathable structure whilst maintaining the same signature feeling of stability and support (and durability) as the Dottore Pro. The result is a our lightest ever pair of shorts, totally breathable but still supportive for the highest performance on all summer rides.

Do you like to feel in control?

Dottore bibshorts are the maximum expression of Q36.5’s approach to high performance, each bibshort in the Dottore range has been engineered to give you, the rider, a feel of maximum support. This support can be immediately noticed in the “locked in” feeling of perfect contact between your chamois pad and saddle and the shorts with your groin area, achieved through interaction between the high modulus force of our woven fabrics and the proprietary two-piece chamois system.

The variable density of the leg panel (with its signature silver yarn), which gives a mild compressive feeling, works to align the muscle fibers of your legs, facilitating a correct elongation and contraction of the muscle, reducing fatigue over long distances.

The result, whilst riding, is that of superior control of your bicycle and pedalling action, as though almost being guided by an invisible teacher or doctor, even in moment of maximum exertion and fatigue.

The superior version of what you already use

The Gregarius range of bib shorts take the pinnacle technologies of the Dottore bib short range and retunes them to create a bib short that at first feels comfortingly familiar, but once on the bike offers you a distinct performance upgrade. This upgrade arrives in the form of comfort (Gregarius uses identical straps, lumbar support panel, chamois, method of chamois attachment to the Dottore), moisture management and, new for 2025, ultra minimal pattern that reduces stitching to the essential. You will be able to stay out longer, in worse weather, than ever before. The ultimate all-rounder.

Go Cargo

For those looking for the ultimate cargo bib short for Gravel Adventures, Q36.5 offers its new Gregarius with two invisible pockets, cut directly into the leg panel of the shorts for an ultra-clean look.

Your first serious bib shorts

The Gregarius Essentual bib shorts distill the R&D of Q36.5’s racing models, the Dottore and Gregarius Pro, into a stripped back package that offers new but comitted riders the perfect bib short to tackle if the most epic rides guided by Q36.5’s signature comfort and stability.

Have you ever driven a concept car?

Winner of the Red Dot technology award when first presented in 2021 and continuously refined ever since, the Q36.5 Unique bib shorts represent the most advanced and technologically cutting-edge application of our understanding of stretch woven fabrics. The Unique bib shorts are in fact the world’s only seamless woven bib shorts, with the entire bib short (with exception of the shoulder straps, attached subsequently) leaving the weaving machine as a single, tubular, piece of fabric with 7 different zones of density. The result is a bib short that offers a heightened experience of the performance philosophy of our Dottore bib shorts. We believe that the Unique in fact offers the maximum return to the rider in terms of the comfort of our patented adaptive chamois, of the alignment of muscle fibers achieved through body mapping as well as durability and moisture management. This is the feeling of wearing the future of high performance cycling bib shorts.
