ProMaster's Deluxe Lens Case LC1 uses thick, semi-rigid foam padding to absorb bumps and bruises. The lid features an overlapping zipper to help keep dirt and dust out. The outside of the lens case uses a durable, heavy duty cordura material while the inside is made of a smoother, gentler nylon that's easy on your lens. A tension strap around the outside allows you to snug the case up for a close fit. You can attach the deluxe lens case to a belt or bag using the belt loop on the back of the case, which employs a hook and loop fastening system to open and close securely. Store your lens cap or filter in the convenient mesh pocket underneath the lid.
