Casual are jackets that are intended for everyday wear in the fall, winter, spring, and summer. Casual jackets will prevent the hand from getting cold and wet when the weather gets tough. The most active material found in casual and hunting jackets is nylon. Nylon is a part of a family of high-strength, resilient synthetic polymers, the molecules of which contain the recurring amide group CONH. There are several qualities that nylon material invariably possesses, and they are the following: exceptional strength, elasticity, resistance to abrasion as well as to damage from a number of chemicals and oil, the capability of being dyed into various colors, resilience and low level of absorbency. Casual jackets are great for recreational wear, seasonal wear, hunting, camping, fishing, and much more. Polar fleece jackets are soft, lightweight, warm and comfortable. Polar fleece jackets are a great alternative to wool, of particular importance to those who are allergic or sensitive to wool.
