The main advantage to this Byron tank top from Hurley (aside from the wicked stripe design) is its ability to be reversed. Not only does it give you practically two tanks for the price of one, but it lets you avoid doing laundry for that much longer since you can just wear it inside-out. It's really a no brainer, though be sure to stand downwind of people, lest they become suspicious. Visit store for more details.
