This sleepshirt offers an exceptional experience unlike any other. It’s crafted with the same weave as our bestselling Signature fabric, which starts with the highest quality, 100% organic cotton threads. The buttery, breathable feel is made even softer with our Luxury Soft-Wash—a gentle process that uses natural enzymes to relax the fibers, drawing out a smoother, more lavish feel—and continues to get softer over time.
