These US-made Goodwear Undershirts are lightweight and super comfortable against the skin – exactly what you want in an undershirt. But they’re also thick enough that your nipples won’t show through them, so they function just as well as shirts, too (without the under part). They’re also tube-knit (fuck a side seam), and come in 2-packs for $48 (and if you buy two 2-packs, you can get a third for free – so that’s six shirts for $96, in case you don’t have a calculator nearby). Two colors are available.
