Occy is still at it. The Billabong Occy t-shirt is aptly named after this surf legend & features a classic Australian Billabong design. The Billabong Occy yellow t-shirt features an arched Billabong logo in fresh green & blue colours. This men’s yellow Billabong tee shirt is a slim fit, so if you prefer your surf clothing not so fitted, it may be worth selecting a size larger than you would normally wear.
