Propper International is introducing three premium apparel collections, including 22 new items overall. The Propper Sweep collection is designed for use in the covert, non-uniform environment. Propper LS1 is engineered to enhance your speed and agility, while Propper CCMF is built to withstand merciless heat and humidity. A portion of proceeds from the sale of all three collections will benefit Sheep Dog Impact Assistance, a volunteer organization that supports military and law enforcement personnel in times of need.
