Our warmest and most protective base layer, designed for riding through the deepest winter. The Thermal Windproof Base Layer features an integrated hood and a windproof front panel for additional protection against wind and cold in demanding conditions.

The windproof front panel protects the chest from direct exposure to the elements, while the main fabric is constructed from Polartec® Power Wool™ with a wool grid backing. The construction combines high breathability with effective insulation, helping retain body heat without adding unnecessary weight.
