Redefining hot weather performance. The Helium Jersey is a super-light training jersey designed for the peak of summer.

The Helium Jersey is a super-light, race fitting jersey designed for riding in temperatures in excess of 20c. Our concept for this jersey was born after a summer of riding in extreme heat in the French Alps in 2019. Back to back hot days on the Galibier, Glandon, Madeleine, Iseran, and Lacets de Montvernier saw our bodies pushed to the limit.

We returned from the Alps and immediately began our search for fabrics that would keep us cooler, and drier when the weather is hot, humid, or even when you're riding indoors in warm environments.

Produced using an amazingly lightweight, Italian open-mesh fabric, this jersey is designed to maximise airflow to the skin, keeping the body as cool as possible. Incredibly breathable and sweat wicking, the Helium Jersey stays cool when the legs are burning.
