Billabong AI Prism (Andy Irons) Boardshorts: Andy Irons has been riding big waves since you were in diapers riding big wheels. Pull on the men’s Billabong AI Prism Boardshort and follow his lead on the breakers. Constructed with Billabong’s Airlite stretch fabric, the Billabong AI Prism (Andy Irons) Boardshorts won’t weigh you down on the water, and the side-to-side stretch prevents bunching when you’re paddling out. The 22-inch inseam won’t let your board burn up your legs, and the mesh cargo pocket holds your essentials when you’re digging your toes in the sand.
