The thing about travel tees is that they are often super thin and stretchy… So if you are chubby, you look more so… and if you are athletic, you look as though you are trying to flex. I prefer my t-shirts to be thick, boxy, and soft enough to be comfortable, but not so soft as to look modern. Does that make sense?
In any case, the 72-hour Merino is about the best travel garment that I’ve found. It’s merino, so you get all the good shit that comes with that. But also, it’s just cut right and you don’t look as though you are wearing travel clothing.
