Well, are they as really waterproof as they say? The picture on the box shows them partially submerged in water. However this weekend I went caving and decided to wear my Sealskinz Ultra Grip gloves which are supposed to be 100% waterproof. Got them somewhat muddy so decided to rinse them in the sink whilst wearing them to get the mud off (i.e effectively washing my hands whilst wearing gloves). The water penetrated them within seconds. Hardly 100% waterproof!
