The ability to effectively layer is an absolute necessity when cycling throughout the winter. The Thermal Long Sleeve Base Layer and its updated collection of colourways provide the ideal foundation for your winter layers. This base layer has been constructed using the innovative Polartec® Power Wool™ fabric. With a merino wool. Interior and a synthetic fibre exterior, we have developed a hybrid base layer with a distinct surface, created to optimize moisture control, breathability, and durability. The premium merino wool makes this piece naturally odour resistant while a high-efficiency grid backer traps warm air and aids in moisture transfer for quick drying.
