Why is the Billabong Women's Sea Clash Tank Top so easy to wear? Maybe it's the cotton and modal blend that's so smooth it feels like you haven't left your bedsheets. Maybe it's the resistance to shrinkage, giving the Sea Clash a breezy, loose fit every time. Maybe it's just the sunny all-over pattern so conducive to days spent on boardwalks and beaches. No one will ever know the exact reason. And, in such a relaxing tank top, no one will really care.
