Rodeo cowboys are not often exposed to the sun, or other adverse weather conditions. But it's not just about protecting the skin from sunburn, it also protects the skin from blisters, chaffing, and skin abrasions. A long sleeve shirt can be worn as an outer layer when the weather is hot, cold, windy or rainy. A long sleeve shirt can also be worn under a vest or jacket to provide additional protection from the elements. It's also a fashion statement. Either way, a long sleeve shirt is an important part of a cowboy's wardrobe and can be worn in a variety of situations.
