While some have an (obvious) rational NOT to like these... I state that there is a reason these were readily adopted by our troops in the current ongoing conflict. They sheild from sun, wind and sand... are considerably warm in the cold and wick away moisture in hot climates (remember, this is 100% cotton). Wash once and line dry to full the material completely and you're good to go!! Will not leave home without this one. Bought 2... one in tan for me and the OD green for my son!!
