Vortex Media Storm Jacket Pro
This is the most economical and easiest solution for keeping your camera clean and dry. The velcro opening can be closed to make a very water resistant seal. The opening on the bottom also makes it easier to get your hand inside the cover to focus the lens manually.
Having a Storm Jacket in your camera bag or stuffed in a pocket is an absolute must for any serious photographer. You’ll have peace of mind knowing that your gear will be protected.
