Slipstream takes the classic mechanic-shirt silhouette and gives it a sharper MMCC identity. The Black/Royal Blue colorway keeps the look deliberate without drifting into disposable uniform territory, while the clean front and workwear proportions make it easy to wear with denim, boots, riding pants, a vest, or a jacket. It belongs in the garage, works for a parts run, and still looks intentional when the tools are put away. This is workwear that knows where it came from without needing a name patch to explain itself.
