Thanks to impossibly lightweight jersey, this three-piece set is breathable and airy, keeping you cool through the night, a dream come true for any hot sleeper. The sleeveless tank has a loose fit and pairs perfectly with the elastic waist and drawstring shorts. And when the alarm goes off, top off the two with the matching tie-waist robe, which will stay securely in place thanks to the added inner ties. Whether you wear all three pieces together or as separates, your lounging is sure to get cooler by a few degrees. .
