For some games this season, AJ Brown has rocked a white arm sleeve. AJ probably wears it for the swag but it’ll also protect him against turf burn and keep his arm warm. It’s a little bit tough to tell what brand it is since there is no obvious branding. My best guess would be Nike because both AJ and the NFL are outfitted by the Swoosh.
