The Canon Lens Case LP1319 is a soft drawstring lens pouch made to protect a Canon EF-S 10-22mm f/3.5-4.5 USM, EF 16-35mm f/2.8L USM or EF 17-40mm f/4L USM lens.
★★★★★ Perfect fit for my Canon 17-40mm f/4L—snug but easy to use. The soft pouch protects the lens from dust and scratches in my bag, and the drawstring closure is simple and secure. Great inexpensive protection.
