• Powerful Insulation: Get ready to combat the cold with our ECWCS Gen III Level II Underwear Top. Made from breathable, mid-weight grid fleece material that is great for layering, the thermal base layer military shirt is designed to keep you warm, comfortable, and dry, even in the harshest winter weather.
• Stay Warm & Dry: The base layer t-shirt wicks sweat and moisture away for optimum comfort, swiftly transferring it to the top layer for a quick dry. This allows you to move freely without your clothing sticking to you, ideal for winter operations, hiking, camping, skiing, snowboarding, hunting, and other outdoor activities.
• Comfortable Fit: Built from a soft polyester / spandex blend, the grid fleece fabric easily flexes and contorts with your body for optimum comfort. The zip collar allows the long sleeve undershirt to be worn as a turtleneck for additional protection. The extended back tail ensures total coverage when crouching or moving, while the thumb holes keep your sleeves in place.
• Active-Duty Approved: The thermal shirt is part of the Extended Cold Weather Clothing System (ECWCS) and is a must-have for any military personnel, tactical professional, or outdoor enthusiast in cold climates. Whether you are gearing up for a mission or camping up in the mountains, you will want to keep a pair on you.
• Better Together: Stay warm and comfortable this winter with our matching ECWCS Gen III Level II Underwear Bottoms. The base layer pants feature the same breathable, mid-weight grid fleece material as the top, ensuring that you’re ready for the mission at hand.
