Having the right undershirt for a ballistic vest in colder weather is crucial for comfort and performance. The 5.11 Tactical Winter Mock Undershirt fits that need with its unique design and features. It is made out of our moisture-wicking, anti-microbial and quick-drying fabric. Our saddle-shoulder construction offers greater range of motion and an underarm mesh panel allows moisture to vent and evaporate easily. The 5.11 shirt has flat-lock seams to reduce friction and prevent chafing. The 5.11 Winter Mock is designed to wear under body armor but is also great for casual and workout wear. The long sleeve Winter Mock is made of a heavy material that will insulate you against the cold. Made of 88% polyester and 12% spandex, the Winter Mock is designed to last. Even after 100 washings, this shirt maintains its shape and color. The loose fit and generous sizing make this a very comfortable and practical shirt. Affordable enough for everyday wear, the Winter Mock is designed to be worn under body armor providing warmth, comfort and protection throughout a long work shift. The durability of the Winter Mock makes this a great value for cold weather wear.Durable, comfortable and functional

"Although this is a good buy and a better buy than UnderAmour's cold weather gear in terms of comfort, the neck is saggy and doesn't look tight and straight like UnderArmour.
I still use the 5.11 shirts, but wear them backwards to keep the neck looking professional."
"I was issued the 5.11 Winter Mock as part of our ERT gear. The loose cut and material weight is perfect as a cold weather base layer. Even indoors with other layers over it (body armor, TDU shirt etc) the winter mock kept me comfortable without overheating.
Even in highly mobile situations the shirt has stayed tucked in and allowed me full range of motion.
The only improvement I would like to see is to have it a little tighter around the neck. Otherwise, a great comfortable piece of gear!"
