Tribal Gear "Hydro Skull" T-Shirt. Tribal keeps you looking good in any of their styles! Since 1989, Tribal has been at the forefront of the "street wear" scene. Our goal today remains the same as it was almost 2 decades ago, to represent the underground internationally from the clubs to the streets without compromise. This Tribal Gear tee features a sick all over design featuring a skull in agony and the Tribal Hydro logo with cobalt & silver flake ink accents. This shirt is covered front, back and sleeves with incredible street splash background and also has the tribal 20th anniversary logo integrated in to the back design.
