Traveling, moving to a new apartment, working from home. At certain points in my life, I've lived in Nike's Tempo Track Shorts ($30). Simply put, they're some of the best gym wear out there.
They're lightweight, moisture-wicking, super comfortable and they come in just about every color you could want. There are probably about seven pairs in my drawer right now that I've amassed over the years, including one with my alma mater's logo and another one repping my favorite pro team. Of course they're meant for running, the gym isn't the only place where they're worth sporting. (No pun intended). [Nike]
