I switched to the genuine product after CANON released its own, so I am selling this. Shipping will be from Monday to Thursday on weekdays. This is a size M rain cover. It protects a digital SLR camera with an F2.8 70-200mm lens when shooting in the rain. It can be stored in a small pouch and doesn't take up much space in your bag, so you won't be caught off guard and stranded by a sudden downpour. canon Canon nikkon Nikon ef rf
