Q36.5 Gregarius Hybrid Big Fade Vest

The Q36.5 Gregarius Hybrid Big Fade Vest is a Pro Team-issue cycling vest built for fall and winter riding, when a full jacket is too much and a jersey alone is not enough. It is made in Italy and aims for Q36.5's usual balance of thermal protection and breathability across a wide range of cool-weather conditions.

Body mapping that covers the back and flanks

Most vests concentrate their wind protection on the chest. Q36.5 takes a different approach here. The thermal, tightly knitted fabric covers the front, the flanks and the back, following the path cold air takes as it moves around your torso while you ride. Q36.5 says its wind tunnel testing led it to extend the thermal fabric across the back for that reason. Strategically placed mesh panels let heat escape so you are less likely to overheat on harder efforts or climbs.

UF Hybrid Shell without a membrane

The vest uses Q36.5's proprietary UF Hybrid Shell, a high-density woven fabric made with silver thread and recycled coffee bean waste. The construction is designed to retain body heat while letting excess moisture out. Its malleable build acts as a wind barrier without a membrane, which Q36.5 says helps breathability. If you have worn a membrane vest that felt clammy once the pace picked up, this is the problem the design is trying to solve.

A familiar fit with Dottore-level technology

The Gregarius Hybrid Vest carries much of the technology found in Q36.5's Dottore line, but it keeps the feel of a classic cycling vest. That makes it a sensible choice if you want a performance upgrade without a kit that feels unfamiliar. The arm openings and hem are left raw and unhemmed. This lets the vest sit smooth against the torso, cuts material bulk and makes it easier to pack into a jersey pocket.

Sizing

The vest is available in sizes XXS through XXXL. Q36.5 advises women to order one size smaller than their usual women's jersey size. For example, a rider who wears a small in women's jerseys should choose the XS vest. Our size chart on the product page lists chest, waist, height and weight ranges for each size.

For fall and winter road rides, the Q36.5 Gregarius Hybrid Big Fade Vest suits riders who want serious wind and thermal protection in a light, packable layer that fits like a traditional vest.
