Q36.5 Gregarius Hybrid Racing Car Vest

The Q36.5 Gregarius Hybrid Racing Car Vest is a lightweight thermal cycling vest designed to block wind and hold in warmth without adding bulk. Q36.5 builds the Gregarius Hybrid vest around a simple idea: protect the parts of the torso that take the most wind, vent the parts that overheat, and keep the whole thing small enough to carry. This version comes in red.

Wind Protection Where It Counts

The vest uses an advanced body-mapping design. Q36.5 pairs a high-density woven UF Hybrid Shell, which is designed to retain body heat, with strategically placed mesh panels that help prevent overheating. The idea is to give you full protection from cold wind across the front of the torso while leaving a way out for heat and moisture once you start working. That balance matters on a cool-weather group ride, where you can be shivering at the start and overheating twenty minutes later.

Q36.5 also lists moisture management among the vest's features, which helps the layer stay comfortable when effort rises.

Light, Packable, Year-Round

The Gregarius Hybrid weighs 160 grams in size M. The hem is a raw finish, which reduces bulk and adds comfort at the edges. It packs into a jersey pocket, so you can start a ride with it on and stash it when the temperature climbs. Q36.5 positions the vest for all four seasons: a windproof layer for spring and autumn mornings, and a light extra layer for cold descents in summer in the mountains.

The fit is unisex, with an ergonomic cut that gives you freedom of movement in the riding position. Q36.5's sizing runs from XXS to XXXL.

Where It Fits

The Gregarius Hybrid vest sits in the Gregarius line, Q36.5's performance range built for riding and racing. It suits riders who want a dedicated wind layer rather than a heavier jacket, and who value a vest that disappears into a pocket when it is no longer needed. If you already ride in Q36.5 kit, it layers easily over a jersey or base layer.
