Q36.5 Rain Shell Aero Jersey

The Q36.5 Rain Shell Aero Jersey is a waterproof short sleeve cycling jersey that Q36.5 describes as the lightest layer in a professional rider's rain system. It is built for riding in the rain without the bulk of a full jacket. At 137 grams in size M, it adds very little weight to a ride.

3-Layer Double-Membrane Fabric

The jersey is made from a proprietary three-layer fabric with a double-membrane outer face and a stretch membrane. Q36.5 leaves the membrane exposed on the outside, which the brand says helps with waterproofing, packability, and an aero fit. A conventional rain jacket hides its membrane behind a face fabric, which adds weight and bulk.

The inner face carries a Quick Dry coating for moisture management. That matters in a waterproof garment, because a layer that keeps rain out also has to deal with sweat from the inside.

Race Fit and 8mm Waterproof Zip

The cut is Q36.5's Race Fit, an aero-oriented block designed to sit snug and wrinkle-free. It runs slightly tighter than the brand's standard fit, so Q36.5 recommends sizing up if you usually wear a small. Check the size chart on this page against your chest and waist measurements before ordering.

The front closure is an oversized 8mm waterproof zip, which Q36.5 says is chosen for reliability and ease of use. A larger zip is easier to grab with wet or gloved hands, and it is one fewer place for water to get in.

Care and Where It Fits

Q36.5 notes that the fabric is delicate and prone to cuts, tears, and snags, and that its color can be naturally uneven. Wash it cold with a delicate detergent, inside out, with the zip closed.

The Rain Shell Aero Jersey comes in White and is made in Italy. It suits racers and training riders who want a light waterproof layer for wet days and a close, aero fit.
