Shooting in or near the desert, the one accessory that I discovered that I really needed was a large dark cloth. I used my Levis shirt most of the time, but definitely will take one on my next trip out west. Cutting down on the glare was a huge problem and keeping my camera out of the direct sunlight was another priority. While the shirt worked well enough, a dedicated cloak would have been better.
