Given that the average person spends around one-third of their day in bed, it’s surprising how little thought goes into what is worn during this time. While people spend hours researching and picking out their daytime clothes, the clothes you sleep in and lounge around in are rarely given nearly as much thought. Of course, unless you’re regularly entertaining overnight guests, style doesn’t need as much consideration. But, comfort definitely does. That’s why the best flannel pajamas for men are finding more popularity this year than ever before.
While it’s easy to default into sleeping in your underwear, any old t-shirt and shorts or nothing at all, actively choosing your nightwear can offer a number of worthwhile benefits. Most importantly, more comfortable sleeping conditions mean a better night’s sleep. And better sleep means a healthier, happier you.
So it’s time to start thinking about what makes you the most comfortable when you’re asleep. And, if it’s cold outside, that likely means wearing a warming set of pajamas, so you can stay cozy and warm all night long. We recommend flannel for chilly nights. But, before we get into the best flannel pajamas for men, let’s first explore flannel a bit further.
What Is Flannel?
In the case of flannel pajamas for men, the popular material is made up of raised fibers which help trap heat inside, making this fabric a great option for the winter or cooler weather. It’s worth noting that flannel still offers a good level of breathability, which helps prevent overheating and maintains a comfortable temperature for the wearer.
Flannel is most commonly produced from cotton but can also be made from wool, fiber blends or other synthetic fibers, such as polyester.
Is Flannel the Same as Plaid?
No, flannel is not the same as plaid, even though you may sometimes hear these words used interchangeably. Flannel is a fabric, while plaid is a pattern. However, the words are commonly used incorrectly because in many cases flannel fabric is sold in a plaid pattern. But, you can also find flannel in several other patterns. For example, you can have a plaid jacket, you can have a flannel jacket or you can have a plaid flannel jacket.
Got all that? Good! We’ve put together our top picks for the best flannel pajamas for men. You’ll find full sets as well as individual shirts and pairs of pants below, so you can be both comfy and warm while you slumber.
