ACERBIS jersey MX J Windy Vent brush

The ACERBIS jersey MX J Windy Vent brush is a lightweight off-road motorcycle jersey designed for hot, high-intensity riding, where ventilation and quick drying matter as much as freedom of movement. Built from technical polyester, it suits riders who want a slim, close fit whether they ride with or without body armor.

Outer construction

This jersey uses 100% technical polyester fabric that offers natural stretch, so it moves easily with your body over the bike. The material feels soft against the skin while still holding its shape during aggressive riding. At just 160 g, it keeps overall gear bulk down, which is useful for long motos or trail days.

Weather protection

While not a rain barrier, the jersey focuses on managing heat and moisture in warm conditions. The technical polyester fabric helps move sweat away from the body and allows air to flow through, so you stay more comfortable as the pace picks up.

Thermal system

The MX J Windy Vent brush is completely made of vented fabric to maximise airflow over the torso and arms. This open, breathable construction helps prevent overheating when riding in high temperatures or during intense off-road sessions. The quick-dry fabric also reduces that damp, clingy feel between motos or after brief rests.

Fit and features

The slim-fit cut is tailored to sit close to the body, giving a neat profile when worn on its own and enough room to accommodate body protections underneath. This closer fit reduces excess fabric that can flap at speed, while the natural stretch of the polyester keeps it from feeling restrictive. It all adds up to a jersey that stays comfortable and responsive through constant movement on the bike.
