Pajamas should be comfortable, not restrictive. Look for a "relaxed fit" that allows for easy movement. The waistband should sit comfortably without digging in, and the length of the sleeves and pants should be just right—not too short, not tripping you up. Always check the size chart provided by the manufacturer, as sizing can vary between brands.

Not all fleece is created equal. Terms like "polar fleece," "microfleece," or "brushed polyester" all refer to variations of the fabric. Polar fleece is usually thicker and warmer, while microfleece is softer and lighter. A good quality fleece will feel dense and plush, not thin or flat. It should also maintain its shape and softness after washing, which is a key sign of good sleepwear material.
