About this product
The Air Jordan 1 Low OG Obsidian UNC GS brings together two beloved Jordan color stories in a scaled down but faithful execution. Deep obsidian anchors the upper, paired with university blue accents that reference Michael Jordan’s collegiate roots. Sail details soften the contrast, creating a balanced and nostalgic look that feels instantly familiar to long time fans. This pair matters because the obsidian and university blue combination has become one of the most celebrated palettes in the Jordan archive. Even in grade school sizing, the design carries the same emotional weight, making it popular among collectors and families alike. It represents continuity across generations, proving that iconic color stories resonate no matter the size, as long as the heritage remains intact. The Air Jordan 1 Low OG Obsidian UNC GS was released on March 29, 2025 with a retail price of $120.
