San Francisco days rarely get hot enough to melt during a run, but intense interval gym classes or studio cycling sessions are another (sweaty) matter. I'm always on the lookout for a shirt that will keep me dry(ish) during gym days, so I've been loving the comfortable, crazy-wicking Adidas Climachill Tee ($45). The all-over mesh-like fabric has tiny holes to keep you ventilated, but what really keeps you cool are the metal dots placed on the inside back of the shirt, which feel great on your skin when you're overheating. The slim yet slightly loose fit and slightly weighted hem keeps me feeling confident that my shirt won't ride up during class; my only quibble is that I wish it were slightly longer to accommodate for my long torso, but that's nothing a midrise capri can't fix!
