OP/TECH USA's neoprene LENS SLEEVE is the latest innovation in lens protection. LENS SLEEVE slides quickly and easily onto a lens and has the option of being combined with any size Hood Hat (sold separately) to create a totally customized system. It comes with a Velcro?-backed tab with a plastic connector that can be secured to the leather tab of a Hood Hat (see photo above). This simple system enables the LENS SLEEVE and the HoodHat to be connected together for added protection. LENS SLEEVE is available in four different lengths (3", 4", 5", 6") to accommodate a wide variety of lenses. For the photographer who uses sunshades and prefers to keep them attached to the lens, the LENS SLEEVE and the Hood Hat make a dynamic combination! Proudly made in the U.S.A., LENS SLEEVE is sure to please!
