We searched the globe for the perfect knit fabric for our pajamas. We started with hand pulled Peruvian Pima cotton, which is known for its silky luster and soft texture. We combined this Pima cotton with Modal to get the perfect drape and added Spandex to give it stretch and recovery so they look and feel great with every wear. These PJs are so luxuriously soft you'll never want to change out of them. 48% Pima Cotton, 48% Modal, 4% Spandex Contrast piping and drawstring Full length PJ pant with pockets Waist has 3/4 inch elastic in the back with a drawstring in the front Machine wash cold / tumble dry low / no bleach This pajama is pre-shrunk but will shrink another 5% when washed Made in Peru This pajama set has a snugger fit than our woven PJs. But the stretch gives it the perfect fit every time.
