What Are Optical Illusion Print Board Shorts?
Optical illusion board shorts, also known as trick-print novelty swim trunks, are a popular category of men's beachwear. They use creative sublimation graphics to create visual deception. The most classic design prints fake briefs underneath the outer shorts pattern, creating a funny, attention-grabbing look. Unlike plain solid-color swim shorts, novelty printed styles focus on entertainment and self-expression, making them viral picks for summer social media.

Fabric & Printing Guide
Most quality board shorts use lightweight 100% polyester. Key features: quick-drying, water repellent, breathable and resistant to chlorine and saltwater.
Dye Sublimation Printing is the standard production method. The ink penetrates into polyester fibers, so the prints stay bright and will not peel or crack after long-time use. Low-cost heat transfer will bubble and fade quickly after swimming.
