Collection: Heavyweight Series

Some shirts you wear. These you carry. The Heavyweight Series is built for riders who know the difference between fabric and canvas — who notice the weight when they pick up the hanger and decide to buy.

Every design in this collection runs on Cotton Heritage MC1086: 6.5 oz combed ring-spun cotton, side-seamed construction, 1×1 rib collar. The same motorcycle DNA as the rest of Mummyduck Customs — just on a shirt that earns its price and keeps its shape.

⚖️ 6.5 oz/yd² (220 g/m²) — heavier than standard, feels it immediately
🧵 100% combed ring-spun cotton — 20 singles, tighter weave, richer print
📐 Side-seamed construction — structured fit that doesn't warp
✍️ Printed on demand in the USA + EU
Sizes S–4XL

Mummyduck Customs Heavyweight Series — 6.5 oz Cotton Heritage T-Shirts

Built Heavier. Designed Harder.

6.5 oz combed ring-spun cotton. Side-seamed construction. 1x1 rib collar. These are not the t-shirts you buy without thinking - they are the ones you reach for every time. Every Mummyduck design. On a canvas that earns its price and keeps its shape.
