Flannel is notoriously cozy, but sometimes, that coziness can have a downside to it. It can, allegedly, make you sweat. But, is this really true about flannel? We researched this to find out the truth of the matter!

While many similar materials can trap heat and moisture inside, causing a sweat, flannel doesn't do that.

Is Flannel Warmer Than Cotton?

This is a little bit of a strange question, simply because most modern flannel is currently made out of cotton. The major difference between most cotton sheets and flannel sheets is the way flannel is made. Flannel is a material made by "napping" the material, which is where it gets that nice, fuzzy texture. Cotton is woven rather than napped. 

Does A Higher Thread Count Make Sheets Hotter?

Because you can't really count the threads on flannel, there is no "thread count" for flannel. This makes it different from most other types of sheets. Rather than the typical thread count you'd see on Egyptian cotton sheets, you will see that flannel is graded by weight. Heavier flannel is considered to be of higher quality, not to mention the warmer option. 

With that said, most sheets that do have a thread count have a trend that suggests it does get hotter. Higher thread counts mean that the fabric of the sheet is going to be denser and softer. This, in turn, means that you can expect it to be warmer at night. While this is usually a good thing, it's worth noting that too much thread count can trap sweat inside.

What Is The Best Weight For Flannel Sheets?

The best weight for flannel sheets can vary from person to person, but on an industry level, 5-ounce or 160 GSM is considered a luxury build that'll be wonderful for winter settings. If you are worried about overheating or prefer a cooler type of bedsheet, you may want a slightly lighter density. 

How Breathable Are Flannel Sheets?

Flannel might have a reputation for trapping warmth, but that doesn't mean that you should expect your sheets to turn you into a sweat machine. Unlike other thick materials, flannel is a fairly breathable material. You can expect most of the moisture that causes sweat to become an issue to stay out of your bed with flannel.

When it comes to sheets meant to keep people super warm, you can't beat flannel in terms of breathability. It's one of the reasons why this material remained popular for over 500 years. 

Are Flannel Sheets Good For Summer?

It depends on the quality of the flannel as well as your personal preference. Because high-quality flannel is breathable while still warm, most people will find it a perfectly acceptable year-round sheet material. However, some people might find that flannel is too warm during hot summer months, simply because of how it can trap heat in. 

If you are the type of person who can't stand too much warmth, you might want to choose a different kind of bedsheet for your summer months. It may be too hot for you, especially if you are prone to getting cranky in heat.
