It's Official — These Are The Coziest Flannel Pj's On Amazon

When you're searching for the coziest flannel pajamas on Amazon, it may be a little tricky to narrow down the options that are truly made of flannel (and not just a scratchy synthetic fabric with flannel's signature plaid design). Though flannel was originally made from wool, the soft, insulating fabric is now frequently made from cotton, making it breathable, durable, and lightweight. Whatever material is being used, the most distinguishable characteristic of flannel is that it's napped or brushed on one or both sides. This is what gives the fabric that super soft, extra cozy feel.

While many options are made with the traditional plaid design, flannel pajamas can come in tons of other patterns (everything from polka dots to penguins). Though, if you see a pair of pj's with a plaid design, don't assume they're made of true flannel. While compiling the list below, I did the research to ensure that all my picks are the real deal and will keep you warm and cozy on even the coldest nights.

Aside from looking at the fabric, you'll also want to think about what style of pajamas is most comfortable for you. My picks below include something for everyone, whether you prefer a loose nightgown, shorts and a T-shirt, or a classic long-sleeve set.

With all of this in mind, read on to find the coziest flannel pajamas on Amazon.

This Classic Long-Sleeve Flannel Set That Comes In Tons Of Patterns

What's great about it: This collared long-sleeve flannel set is both classic and ideal for cool weather. Made of 100% cotton, the warm fabric is super soft, and it's also pre-shrunk, which means it will maintain its shape well in the wash. The top has a button-down design while the pants have pockets and an elastic waistband for a secure and comfy fit. Reviewers note that this set runs a little big, so if you don't like a loose fit, it may be best to size down. It also comes in 17 colorful patterns, including penguins and snowflakes, so you can find one you love (or a few).

One reviewer wrote: "Very comfortable and cozy. I originally bought one pair, but loved it so much that now I have four pairs of these in different patterns. Highly recommended."

A Full-Length Flannel Nightgown That’s Warm And Flowy

Made of 100% cotton flannel that's double-brushed, this nightgown is lightweight and breathable while still offering plenty of warmth for cold nights.

This set comes in six different patterns and color combos, and it's a hit on Amazon, with a 4.6-star rating.

One reviewer wrote: "I love this set! The t-shirt is a nice, heavier weight. The flannel shorts are cut roomy, but are super cute. I'd suggest sizing down one size, but I don't mind a little extra roominess since they're pajamas. I'll be buying other colors for sure."
