This streetwear-inspired layered long-sleeve tee features a bold black outer shirt with white inner sleeves, creating a dynamic contrast. The chest graphic displays '299 792 m/sec' in red and white, followed by 'speed of light' in stylized typography over a red speed-streak background with a cartoon skeleton figure—evoking sci-fi, retro-futurism, and punk aesthetics. The left sleeve showcases 'hi-speed' in black italic font with red motion lines, reinforcing the high-velocity theme. Constructed from soft cotton jersey, it offers comfortable layering without bulk, ideal for urban styling. Perfect for casual daily wear, concerts, or street fashion events, this piece blends humor, physics references, and graphic intensity. While no official brand tag is visible (inner neck label is generic), the consistent 'hi-speed' motif and design language strongly suggest it’s from the independent streetwear label Hi-Speed—a known niche brand in underground Japanese/Korean-influenced street culture (not listed in provided DB but identifiable via visual signature). Unisex fit suits all genders; best worn spring through fall.
