The navy RainCap-Small from LensCoat slides over the front end of your lens to protect its front element from rain, snow, dirt, dust and sand. It is made from the same waterproof, breathable, lightweight poly tricot material as the LensCoat RainCoat 2. It includes a tether to attach it to the RainCoat and can be folded and stored in the RainCoat pouch. Tape-sealed seams keep moisture out and an adjustable bungee cord keeps the RainCap in place. The RainCap-Large covers lenses with front diameters up to 5.25".
