Q36.5 Air Jacket

The Q36.5 Air Jacket is a lightweight cycling wind jacket made in Italy. Q36.5 designed it to protect against wind and light rain, and to keep riders comfortable in changeable weather through the year. It weighs 90 g in a medium, and the brand lists it as a four-season layer.

Fabric and Weather Protection

The jacket is cut from a high-density stretch woven fabric, made of 80% polyamide, 10% elastane and 10% polyurethane. A durable water repellent (DWR) treatment on the surface is meant to shed light rain. It is not a waterproof shell, so think of it as protection for a passing shower rather than a long wet ride.

Q36.5 says the tight weave also gives wind protection on fast descents and in high-altitude terrain. The fabric has some insulating effect while staying light, according to the brand, which makes it useful for a cool start or a long drop off a climb.

Packability and Fit

The Air Jacket is built to be stowed in a jersey pocket. Q36.5 describes the construction as extremely low-volume, and the idea is that you carry it on every ride, just in case. If the weather turns, it is there.

The cut is body mapped and pre-shaped, so the jacket sits close to the torso and doesn't flap in the wind. The woven fabric has 4-way stretch, which allows free movement in a riding position. Reflective inserts on the back and along the camlock zipper add visibility in low light.

Where It Fits

This Q36.5 jacket is a wind layer for road and gravel riders who want something light enough to leave in a pocket. It comes in Nautica Blue, Ice Grey, Black, Optic White and Poppy Orange, in sizes XXS to XXXL. The fit is close, so check the size chart before ordering.
