Add some knee-saving warmth to a cold start. The fabric uses a permanent water-shedding technology to coat the fibres not just the surface. It retains repellency when stretched and won't get saturated in heavy weather. Made of Elite Thermal Fleece with PI Dry for dry warmth, stretch and durability. Wide elastic binding with silicone gripper keeps them comfortably in place. Anatomic fit prevents bunching. Reflective details for low light visibility.
