How does the Raceday 4.0 Jersey fit, and which size should I pick?

It’s a race fit: close to the body, for an aggressive position on the bike. Measure your chest at the fullest point and your waist at the slimmest, then check the size guide (for example, M is 96–101 cm chest and 82–87 cm waist). If you like riding race fit, choose the size you normally wear in race-fit kit. If you're not sure, choose a bigger size.

Which temperatures is the Raceday 4.0 Jersey for?

We rate it for roughly 10 to 30 °C and hot conditions: a breathable summer race jersey that releases heat quickly during hard efforts. On cooler starts, add a gilet or arm warmers.

Velodrom sizes by body measurements: chest around the fullest part, waist around the slimmest. Our jerseys are a race fit, and this chart uses the same measurements as Pas Normal Studios’ men’s chart, so your PNS Mechanism size is a good reference.

How to measure

Chest: around the fullest part, under the arms. Waist: around your natural waistline. Hips: around the fullest part. Keep the tape snug but not tight.
