The t-shirt is where most men’s wardrobes quietly fall apart. Not because anyone is ignoring it, but because it looks simple enough that people stop thinking about it. A bad one goes boxy in the wash, loses its color after six weeks, and makes everything worn over it look worse by association. We’ve spent enough time on this to know that the difference lives in the weight of the fabric, the cut through the shoulder, and whether the crew neck holds its shape after repeated wear. Crew or v-neck, those details matter more than the logo or the price tag. We’ve been looking specifically at options that work as a base layer under an open shirt, hold up on their own in warmer weather, and don’t look disposable after a season. Some of these cost more than a t-shirt feels like it should. They are worth it. The ones that aren’t did not make this list.
