Dude, the trouser shorts have got to go.
Not only is the Billabong Plaid Zero Board Short superior to most board shorts, but it's waaaaay better than those cut-off pleated trousers you've been rocking. If you're one of those people who think that all board shorts are essentially the same, throw on the Plaid Zero next time you head to the water. You will instantly notice the insanely light Zero Gravity stretch micro-weave in the Platinum X Quad-stretch material. Shortly after you exit the water, you will notice the H2 Repel coating going to work to keep you dry and rash-free.
