Not sure if there are analogous workout shirts and shorts but the ExOfficio Give-N-Go boxer briefs are the most travel friendly item I own. They're sorta like Under Armour material but even thinner and lighter so they can be hand washed or air dryed insanely fast. Definitely looking to get more clothing that fits in that category.
