In celebrating 13th Witness‘ contributions to music and street culture, Los Angeles-based design labelStampd has constructed a long-sleeve jersey to honor the stalwart photographer. Self-taught and originally hailing from Brooklyn, 13th Witness – neé Timothy McGurr – grew up immersed in hockey culture. Recognizing this, Stampd created a lightweight, longsleeve silhouette; a slimmed-down reiteration of traditional hockey tops. The front panel, adorned with “13,” is composed of mesh, while the sleeves are crafted with a poly-nylon blend. In familiar Stampd monochrome fashion, the shirt features a white American flag detail at the left arm, while the right cuff bears an embroidered avocado emblem. Pick this number up from Stampd online beginning June 24.
