One of the best ways to feel toasty warm while sleeping or lounging is to slip into a pair of cozy flannel pajamas. There’s a huge selection of them on Amazon, and whether you’re a fan of plaid, other prints, or solid colors, the
best flannel pajamas will keep you warm and comfortable with soft, lightweight, and breathable fabric.
When you think of “flannel pajamas,” you might imagine a plaid long- sleeve top with matching pants. While that's a classic flannel PJ set, there are plenty of other flannel pajama styles to choose from and many other prints, too. A flannel nightshirt or flannel shorts can give you warmth and comfort without covering you in fabric. If you don’t like matching sets, you can also opt for comfy flannel pants to pair with your favorite tee. I've included a wide range of picks to cover a range of styles and temperatures.
Most flannel pajamas are made from cotton which is durable, very breathable, soft, and stretchy. Cotton is also
usually a safe choice for those with sensitive skin. However, the material can shrink in the wash, so even though these picks are machine washable, it’s best to wash in cold water and follow the drying instructions carefully.
With all that in mind, these are the
best flannel pajamas on Amazon in a variety of styles, sizes, and colors to keep you super cozy.
