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 cotton flannel that we use for our shirting, and they feel really good against the skin. The construction details are the same, too — 22 stitches/inch, flat-felled seams — so they're a worthy investment. We especially like the pockets, which are perfect for your phone, melatonin gummies, spare change, or anything else you like to keep handy around bedtime. Each set comes enclosed in a medium-sized pouch that you can use for things like charger cords and socks when traveling.
