The Cat's Pajamas team searched the globe for the perfect knit fabric for their pajamas. They started with hand-pulled Peruvian Pima cotton, which is known for its silky luster and unbelievably soft hand. We combined this Pima cotton with Modal to get the perfect drape and added Elastane give it stretch and recovery so they look and feel great with every wear. This nightshirt so luxuriously soft you'll never want to change out of it. You might love the matching flannel or pima knit robe, classic or capri pajama set or our long sleeve short set.
