The Extended Climate Warfighter Clothing System (ECWCS) was designed to protect soldiers operating in cold weather climates. The system includes many different articles of clothing including parkas, trousers and headwear, and is built to perform in temperatures ranging from -60 to 40 degrees F. While originally crafted for the U.S. Military, ECWCS clothing is popular among tactical operators, hunters, hikers and anyone who works in harsh weather. ECWCS clothing fights more than the cold. It also protects from wind, rain and snow. Many ECWCS clothing options feature performance-boosting features such as reinforcements in high-stress areas, vents to enhance breathability and moisture-wicking linings to keep you comfortable when you’re on the move. You can tackle anything the weather can throw at you with ECWCS clothing.
