You're out and a shoot and it's going great, but then suddenly the sky grows dark, lightening strikes, and before you know it it's raining cats and dogs. What to do?

Lucky for you, you have a Spider Monkey Rain Cover right at your hip! You quick-draw your Rain Cover from your belt, unfurl it and cover your camera and 70-200mm lens. Nice. Your expensive gear is protected from the elements, you breathe a sigh of relief, and pat yourself on the back for being properly prepared.
