Portabrace 4-inch Lens Cups are lightweight, easy-to-use, protective covers for protecting lenses and other fragile camera accessories. Lens Cups now have a semi-rigid frame for increased protection and are padded with soft poly-fill and have a Nylon interior lining. The lid features a clear vinyl window to help quickly recognize contents and zippers closed for added protection. Each lens cup has an adjustable belt-loop so that it can be removed from the case and worn on a belt for easy access to spare lenses when shooting.
