We do not, under really any circumstances, need another goddamn dress shirt. Not a chambray one. Not a plaid one. Not a single, solitary one. Aside from minor variations in color and fit, most of the ones we own are pretty much the same â and we’re fine with that. But the decades-old brand GANT is making the case that we should clear a little space and pick up a few pieces from its new Tech Prep Line, which the company claims will come in handy when youâre sweaty but donât want to be.
