We take fabric seriously, especially when it comes to the kinds of basics you wear every single day. Or night! These pajamas are made from the same soft, fine Portuguese poplin that we use for our shirting. The construction details are the same, too — 22 stitches/inch, flat-felled seams — so they're a worthy investment. The top has a rounded collar, a button front, and three patch pockets, while the bottom has an easy elasticated waist that just pulls on.
