Hawker trousers are stretchable, windproof and waterproof. They are made from a highly flexible three-layer fabric, combined with the new, stretchable, windproof and waterproof SEETEX® membrane. They also have articulated knees in an extra stretch fabric and high thigh pockets. The trousers have excellent breathability. The inner has a honeycomb texture to facilitate air circulation. This, combined with the breathability of the membrane and outer fabric, distributes air and moisture over a greater area, for quicker evaporation. There is zipped ventilation at the knees for extra airflow when needed.
