On gameday, Deebo Samuel wears a McDavid Padded Arm Sleeve. Deebo almost always rocks all his accessories in all white so of course, this sleeve is white. Sometimes he switches it out for a red one.
The McDavid padded arm sleeve is one of the best in the game. They offer a super clean look, tight fit and good elbow protection.
You can get the sleeve for $25 from Eastbay.
