What to look for in cotton pajamas:

Type of cotton

Though it may seem like all cotton is the same, there are actually several different types that impact the fabric's softness, warmness, and look. Here, I break down the main ones you'll see in cotton pajamas, below:

• Organic cotton: Low impact on the environment due to not using pesticides or chemical fertilizers to encourage growth.

• Pima cotton: Super high quality and known for its incredible softness, durability, and wrinkle resistance due to the longer fiber.

• Flannel cotton: Soft, slightly fuzzy fabric that is best known for its warmth and is great for cooler climates/months.

• Cotton poplin: Cooler and crisper, feels worn-in, and is a great option for summer months.

And remember, cotton shrinks, so it's best to follow the care instructions for the individual PJs—as a rule of thumb, hang dry them.
