I'm yet to find a nice quick-dry pant that isn't stereotypically "outdoorsie" but for shirts, I love the omni-wick line from Columbia. The T-Shirts are by far some of the most comfortable shirts I've ever bought, and they're fantastic for keeping cool and dry. I've noticed they also don't hold the smell/feel of sweat so I've been pretty comfortable wearing them multiple days in a row while camping (I'm definitely not the kind of guy who normally does that, one of my pet peeves is re-wearing sweaty feeling clothing). Same can be said for their button downs, as long as you avoid the PFG branded ones, they look like pretty normal relaxed fit button up shirts but they're super breathable. I wear them anywhere from the office to sea kayaking and they've held up phenominally. All of that being said they're stupid expensive normally, I probably wouldn't own them if I didn't get really nice discounts on Columbia gear through work.
