Having the right undershirt for a ballistic vest in colder weather is crucial for comfort and performance.  The 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 shirt has flat-lock seams to reduce friction and prevent chafing.  The 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. 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.
