Nigel Sylvester x Air Jordan 4 'Grey Mamba'

Two legends. One silhouette. The Nigel Sylvester x Air Jordan 4 'Grey Mamba' merges the world of professional BMX with Jordan Brand's iconic AJ4 DNA — a collaboration built on shared values of fearlessness, precision, and relentless pursuit of the craft.

A grey and black palette keeps the build clean and purposeful, letting the story speak through the details. The colourway pays homage to the 'Grey Mamba' — a nod to the late Kobe Bryant and the grey Nike Mamba colourway he famously wore — filtered through Nigel Sylvester's BMX-informed design perspective. Premium construction throughout, with the AJ4's signature mesh netting side panels, plastic wing eyelets, and visible Air heel unit all present and accounted for.
