The OILSKIN BALLCAP is constructed from the same stuff that makes our coats so great - MicroWax Oilcloth - so it'll keep your noggin dry when its wet out.
12oz. MicroWax Oilcloth 100% Cotton
Products made using the MicroWax cloth are as tough as they come - 100% waterproof, windproof & breathable. Since the blend is not water soluble, any incidence of water to touch it simply runs straight off. The use of a super tight weave of cotton canvas ensures that it is completely windproof. The breath-ability arises from the fabrics crystalline structure which varies and aligns with an increase of body heat, thereby allowing sweat in the form of water vapor to escape.
