Cotton Pajama Sets

Cotton is naturally soft, breathable, and lightweight, which helps regulate body temperature throughout the night. Cotton pajama sets allow air to circulate and wick moisture away, making them comfortable for year-round wear.

Old Navy carries a wide range of styles including poplin pant sets, poplin short sets, snug-fit printed sets, ribbed pajama sets, ruffled tank and shorts sets, eyelet sleep sets, and even 4-piece and 6-piece mix-and-match options for toddlers and babies.

You'll find cotton pajama sets for women's pajamas, men's pajamas and loungewear, kids, toddlers, and babies — so the entire family can enjoy comfortable cotton sleepwear.

Prices vary by style and age group. Toddler and baby sets start as low as around $8.49 on sale, while women's poplin and flannel sets typically range from about $22 to $50 at full price, with frequent deals offering 50% off or more.

Poplin sets have a relaxed, airy fit that's great for warm sleepers and lounging, while snug-fit sets are designed to fit closer to the body — ideal for toddlers and kids who need a secure, comfortable fit for safe sleeping.

Lightweight cotton fabrics like poplin are especially breathable and cool, making poplin pajama short sets and tank-and-shorts sets excellent choices for warmer months.

Yes, you'll find a variety of playful prints along with licensed character sets featuring Disney, Marvel, Pixar, Paw Patrol, and more — especially in the toddler girls' pajamas and boys' pajamas collections.

Cotton pajamas are generally easy to care for — machine wash in cold water and tumble dry on low to help maintain softness and prevent shrinkage. Always check the care label on your specific set for best results.

Many Old Navy cotton pajama sets come in coordinating colors and prints that make it easy to mix and match tops and bottoms for a personalized look, whether you're heading to bed or lounging around the house.
