PIG Mildew-Resistant Absorbent Socks are essential for your hurricane preparedness and response programs. They quickly absorb intrusive water, are flexible and can be left out long-term. The 100% polypropylene skin and filler both resist the growth of mildew - plus the skin resists tearing and holds in liquid, even when fully saturated. The best part? Air-dry the Socks and put them back to work! They can be reused up to three times.
