Whether you’re sourcing Yupoong® 6606 caps for your brand, building a wholesale caps order, or simply looking for the best retro trucker cap on the market, this guide covers everything you need to know about one of Yupoong’s most iconic models.
What Is the Yupoong® 6606?
The Yupoong® 6606 — officially known as the YP Classics® Retro Trucker Cap is a mid-profile, 6-panel structured cap with a curved bill, snapback closure, and breathable mesh back panels. The Yupoong® 6606 takes the timeless silhouette of the classic trucker hat and elevates it with premium materials, precise construction, and a finish that works equally well for everyday wear, custom branding, and wholesale headwear programmes. It is available in one size and a kids size, with an adjustable snapback that fits a wide range of head sizes, making it one of the most versatile Yupoong® caps in the entire catalogue.

Why the Yupoong® 6606 Retro Trucker Cap Stands Out
1. A Classic Silhouette, Refined
The trucker cap has been a staple of casual and workwear fashion for decades. Originally worn by farmers, truckers, and outdoor workers for the ventilation provided by the mesh back The Yupoong® 6606 Retro Trucker honours that heritage while applying modern production standards. The result is a cap that feels authentic without sacrificing quality, a difficult balance that few manufacturers achieve consistently.
2. Premium Mesh Back Construction
The rear mesh panels on the Yupoong® 6606 are more than a stylistic nod to its roots. They serve a genuine functional purpose, promoting airflow and keeping the cap breathable in warm conditions. This makes the Yupoong® 6606 trucker cap a practical choice for outdoor environments, events, and active use, not just a fashion item.
3. Structured Front for Superior Embroidery Results
One of the most important features for brands and decorators is the structured front panel. The hard buckram construction holds its shape during the embroidery process, ensuring clean, sharp logo placement without puckering or distortion. If you are looking for a Yupoong® trucker hat that performs well in production, the Yupoong® 6606 is consistently one of the most recommended blanks in the industry.
4. Permacurv™ Bill Technology
The curved bill on the Yupoong® 6606 features Permacurv™ technology — a Yupoong innovation that maintains the bill’s curve over time without springing back to flat. This is particularly important for caps that are stored, shipped, or worn regularly, ensuring the profile looks consistent every time.
5. Available Across a Wide Colour Range
The Yupoong® 6606 is available in an extensive range of colours — from core neutrals like black, white, navy, and charcoal to seasonal additions including caramel, evergreen, cranberry, silver, and pink. This breadth of colour options makes it straightforward to match brand palettes or offer a comprehensive retail assortment.

Yupoong® 6606 vs 6606T — What Is the Difference?
The Yupoong® 6606T is the two-tone version of the Yupoong® 6606.
