Sandtiger sharks have no eyelids and swim with their mouths open, displaying their three sets of pearly whites. They're also the only sharks that will gulp air to maintain a neutral buoyancy in the water, which helps them hunt their prey in super stealth mode. The Sandtiger, quite obviously, is the most awesome shark ever. You're the most awesome surfer ever (or so thinks your little brother) which makes the Sandtiger rashguard from Rusty a perfect choice. It features a screen print graphic on the chest. Time to hunt down those waves, buddy. You've worked up a mighty big appetite for them.
