The Billabong R U Serious Boardshorts are as serious as a heart attack when it comes to getting wicked in the water. Billabong constructed this short using eco-friendly Recycler Hydrostretch fabric and H2 Repel, which is a water-repellant coating that helps you thrash without getting the rash. The X Quad stretch technology allows the short to bend and flex so you can get gnarled and wrenched like an amphibian-arachnid, super-hybrid mutant surf machine…or something like that.
