When it's hot as balls out, you want as little on as possible. But you can't always wear shorts. Some guys are passionately against them, while others love them but only view them as appropriate for particular times and places. Perhaps your work prohibits them or you simply don't want to be the only guy flashing your calves at the office. But if you choose wisely, you can still wear pants—you just want to be sure you're pulling on breathable, featherweight chinos and jeans made especially for summer (crafted from thinner denim with stretch, along with sweat-wicking properties). Because if you don't, there's no doubt you'll be sweating through your pants by lunch.
