I can't believe nobody here has mentioned high performance merino wool. Super comfortable, holds no odor at all, dries fast, can be re-worn multiple times. One shirt, one pair shorts, one pair socks can last an entire week (or more) with multiple workouts. Hang on doorknob after workout and dries as fast as polyester. Wash in sink if you like, or just bring home and launder after trip. Not cheap, but worth every penny -- total paradigm changers. There are a few manufacturers, but i prefer Icebreaker brand:
