Every great adventure starts with a map — and now you can wear yours. DM's Original Map is Caster Coast's premium D&D board shorts featuring original Dungeon Master cartography artwork that marks you as the architect of worlds, whether you're running a session or running to the shore. Sophisticated D&D swimwear that doesn't look like a costume.
Built for real activity — not just the aesthetic:
The DM's Original Map design is built around hand-drawn cartography iconography — the kind of artwork that signals world-builder to anyone who knows, and reads as premium athletic apparel to everyone else. The best D&D board shorts don't announce themselves. They reward a closer look.
Every pair is produced specifically for your order using premium sublimation printing that resists fading through saltwater, chlorine, and UV exposure. No overproduction. No compromised quality. The result: D&D swimwear that performs as well as it looks.
Yes. The 4-way stretch recycled microfiber fabric, anti-chafe mesh liner, and quick-dry finish are engineered for real water activity — surfing, paddleboarding, beach volleyball, or open-water swimming. The elastic drawcord waistband keeps everything secure during dynamic movement.
Sophisticated. The DM's Original Map artwork is cartography-based and pattern-driven — it reads as premium athletic apparel to most people, and as a clear signal to anyone in the tabletop community. Think editorial swimwear, not costume.
Three things: design intent, material ethics, and community. Original artwork built specifically for the D&D and tabletop RPG community, 91% recycled polyester construction, and on-demand production to eliminate waste — a niche no mainstream swimwear brand has served with intention.
The DM's Original Map board shorts run 2XS through 6XL. See the full size guide below with exact waist and hip measurements. When in doubt, size up for a more relaxed fit.
Yes. Every pair is produced on demand to eliminate overproduction waste. 91% recycled polyester fabric and no excess inventory — a thoughtful choice for the conscientious adventurer.
