The Thermal Long Sleeve Base Layer provides a warm and breathable foundation for winter layering. Constructed from Polartec® Power Wool™, it combines a premium merino wool interior with a durable synthetic exterior for effective moisture management and temperature regulation.

A high-efficiency grid structure traps warm air while helping transfer moisture away from the body for faster drying. The merino wool interior also provides natural odour resistance, making the base layer well suited to long winter rides.
