Q36.5 Gregarius Winter Jacket

The Q36.5 Gregarius Winter Jacket is a winter cycling jacket built for cold days when you still want to ride hard. Q36.5 positions it as a modern take on the classic softshell: close-fitting, light, and aimed at riders who find a bulky insulated jacket too much for fast, mostly dry rides.

Insulation without the bulk

The body and outer arms use a two-layer fabric with a lined membrane, combined with Q36.5's proprietary 3D Air Insulation. The idea is to trap warmth and block wind while staying thin enough to move in on the bike. Retailer listings describe it as suited to temperatures down to around 0°C, and reviewers note that it stays light for the warmth it offers.

The fabric blend is mostly polyester with polyurethane and elastane, which gives the jacket stretch to follow your position on the hoods or in the drops. The cut is close to the body, so there is little loose fabric to flap at speed. It has a full-length front zip and no hood, which keeps it neat under a helmet.

Pockets and visibility

Deep rear pockets are easy to reach while riding, and reflective details help with visibility on short winter days. It is a better fit for dry cold than for sustained rain, so on wet days you may want a dedicated waterproof shell instead.

Where it fits

The Gregarius sits in Q36.5's winter range as a fitted, performance-oriented option for training rides, group rides, and cold-weather racing-style outings. It comes in Black and Ice Grey, in sizes XXS through XXL. Check the size chart before ordering, as the cut is trim.
