Shurhold PVA Shammy Towel 220Shurhold PVA Towels absorb 50 percent more water than natural chamois, making for faster and more effective drying. PVA is a high-tech, synthetic material that is lint free and resists mold and mildew better than a regular sponge or towel. The towels prevent water spots on all surfaces and come in an extra large size of 17" x 27" (43 cm x 69 cm).
