Swat T-Shirt featuring artwork and the latin phrase “VINCULUM UNITATIS” which means “The Bond of Unity.” Great Swat Shirt for any Swat Officer or fans of Swat Shirts. Artwork by Julie Robertson. The design is on the back of the shirt. We print this design on the American Apparel t-shirt because it is the smoothest and softest t-shirt you’ll ever wear. Made of fine jersey, it has a durable, vintage feel. These classic-cut shirts are known for their premium quality, as well as ability to stand up to a washing machine (will keep size and color after many washings). The shirts are 100% fine jersey cotton. Great Swat Shirt for any Swat Officer, Police Officer, and fans of Swat Teams.
