Performance doesn't stop on dry land with CURL II. Designed for extreme performance in a wet or dry environment, Dirty Dogs marine grade standard takes into account the devastating effects of the outdoor environment and takes extreme measures to ensure optimum performance. Equipped with a detachable strap, hydrophobic coating on the lenses, water and fog elimination vents. It also floats. “I purchased a pair of Dirty Dog Wetglasses for sailing holiday in Greek islands. Hit by a sudden storm sheeting rain and hail and gusting 40 knots. Visibility zero. Without hydrophobicc lenses it would not have been possible to see the wind direction needle shift in the vortex and keep the yacht head to wind. Lucky to escape with just a shredded Genoa sail.” Mark Spurrell Product Code : 53397
