The T.K.O. Mechanism Thermal Jacket is perfectly suited for cold and wet conditions. The Windtex Pro Membrane used in the 3-layer main fabric adds a high level of stretch and provides an optimal, tight fit for hard-paced training. The DWR treatment of the fabric and the taped seams adds an extra layer of protection from the elements. To enhance wicking and insulation, we use a grid fleece structured backer on the inside of the jacket. The laser cut finishing on both the hem and sleeves gives a sleek look while minimising chafing and rubbing - providing comfort throughout your ride.
