Blue is doing a lot of work in menswear right now and the sweatshirt is where it shows up most usefully. Not because blue is a trend but because it photographs well, sits cleanly with grey, navy, olive, and black, and reads as intentional in a way that a plain grey marl simply does not. The problem with most sweatshirts is that they give themselves away immediately. Thin fabric, poor shoulder seam placement, a hood that sits wrong. They look cheap because they are cheap and there is no recovering from that. What we went looking for here were pieces where the weight of the fabric, the fit through the chest, and the finishing around the cuffs and hem do enough to make the price hard to guess. Some of these are genuinely affordable. None of them look it. Blue is a color that rewards a bit of considered buying and these are the sweatshirts that prove the point.
