"This is my performance trunk…When I'm surfing, I need something that's not going to get in my way, and when I wear these, I almost don't notice that they're there. The seams are [fused] together, so the shorts are basically seamless. They have a slimmer cut and are a bit shorter, so they don't ever catch on your knees. We went through a lot of trial and error with the materials for the trunks, and this material won't cause any type of rash, no matter how long you surf in them." – Kelly Slater
