5.11 UNDERGEAR 5.11 Undergear has been designed from the ground up with the law enforcement professional in mind. 5.11 Undergear is designed and built to provide the comfortable support you need for your 8, 10, 12 or more hour workday. This year we’re introducing three new Undergear garments: tight and loose fitting vneck t-shirts and a winter-weight mock-neck shirt. We encourage you to compare our 5.11 Undergear side-by-side against the other guys.
