These trousers are made from our proven Hydrapel fabric, designed to be tough and durable to withstand harsh conditions. The Macaulays are an all-weather hunting trouser that will maintain a comfortable body temperature even on the hottest days and when paired with a warm base layer, will keep you comfy in the winter. The articulated knees make for optimum movement when kneeling and climbing and the quiet outer makes stalking a quiet operation.
