The Proof of Purchase is a special headwear item for all classes. It appears as an olive green Brodie helmet with slight battle damage and Team Fortress 2 logo of a slightly darker shade emblazoned on the side. A narrow belt with a gold buckle extends around the back, over the wearer's neck.

This hat is available to those who purchased Team Fortress 2 before the Über Update on June 23, 2011, those who receive a gift of the game and those who activate a retail copy of the game.
