Wearing your sweaty, old, hole-ridden, grease-stained climbing T-shirt to the margarita spot after a day in the hills isn't going to score you any points with the fairer sex. (We keep doing it, and look at us. Jeez.) Rack up just a little style cred with the prAna Men's Diamond Back Short-Sleeve Shirt. This light organic cotton button-down isn't too fashion-y, but it definitely has enough curb appeal make you presentable. Just button 'er up and go.
