When you face wind, rain, and cool temperatures on the mountain or elsewhere, you need an indomitable jacket to protect you from whatever Mother Nature throws your way. Insulating options, such as down, perform best in the most frigid temperatures you encounter. Durable canvas and less insulating materials work well in moderately cool temperatures, and they protect you from scratches when you brush up against rocks or trees while hiking. Mountain Khaki's coats are designed for field work and other activities, but they also have fashionable enough appearances to wear around town. Most come in classic solid colors, such as olive, khaki, black, blue, grey and brown.
