This is a simple jet cap. While regular caps are made of six or eight panels, the jet cap's design is characterized by its five-panel construction. Compared to a typical baseball cap, the silhouette is slightly shallower, and it usually has ventilation holes on both sides. It seems like a fresh option for those who are a bit tired of cap-style items.
