You're an easy-going guy who loves chasing swells all summer, but it can't always be sunshine and warm weather. That's where the Billabong 2mm Revo Interchange Jacket comes in, with just the right amount of insulation for the days that are slipping into fall. It features all the stretch you need for balancing on your board, and is built with glued and blindstitched seams to prevent flushing as you paddle. An elasticized waist provides a secure fit when you're out, but it also comes with a board short fastener to keep it in place. Billabong was thoughtful enough to make it reversible as well, so you can switch between solid and print depending on your mood.
