The POLAR LAYER is designed to transform winter riding by acting as a dedicated mid layer worn over a base layer and under a jersey or jacket. It provides the additional warmth cyclists have needed for decades. Constructed from cosy, soft polar fleece material, it traps a layer of warm air while simultaneously transporting sweat away from the body, offering exceptional comfort in cold or wet conditions.
When worn over any Spatz base layer, the POLAR LAYER delivers unprecedented warmth despite its minimal weight and bulk. It replaces multiple garments yet remains feather light and dries extremely quickly.
The close cut is designed to fit under or over bibs, with a sculpted rear that sits low for maximum warmth. This allows riders to choose a lighter or more aerodynamic outer layer while relying on the POLAR LAYER for insulation.
A 3/4 length zip provides easy use and temperature regulation while ensuring comfort next to the skin or under bib tights. It is purpose-built for riding.
