Our Oil Only socks have a white spunbond outer skin with a recycled hydrophobic absorbent filling. These offer fast absorption of Oil Only liquids and act as a containment barrier for any incidental spills. The hydrophobic properties within our Oil Only socks allow the sock to float on water and collect/absorb oil-based liquids from the surface without absorbing any water. These are ideal for use outside where standing water may be present Units in Pack: 8 Size: 7.5cm x 3m Absorbency: 11.25L Per Sock Absorbs: Oils Only 7050
