What Are Flannel Sheets?
Flannel sheets are regular bedding sheets that go through a fiber-brushing process to make them softer. They can be made from different types of fibers, such as wool, cotton, or synthetic fibers, only they are softer because the fabric is brushed to raise tiny fibers to the surface of the sheets. This makes them nice and cozy, but also very delicate when brushed against the skin.
The exact name of the process is called “napping” and it basically implies using a fine metal brush to raise the aforementioned fibers. This texture is more than just soft on the skin; it also helps trap air and provides better insulation because of that. If you want the highest quality flannel sheets, look for those that are napped on both sides.
Are Flannel Sheets Warmer than Cotton Sheets?
Long story short, yes. Cotton sheets are typically designed to be more breathable and soft on the skin, and they don’t necessarily focus on providing the sleeper with a particular sense of warmth. There is a good reason why flannel is a top choice for colder seasons. However, because we care about you being an informed shopper, we have to specify the fact that not all flannel sheets are created alike, and it’s important for you to know the differences between the fabrics used to make them:
- Cotton is a very common material used to make flannel sheets. Flannel sheets made with cotton are really good at wicking away moisture, but also at retaining heat and making sure that you get that nice and cozy feeling every time you lay down on them and under them.
- Wool isn’t that commonly used to make flannel sheets because it’s an expensive fiber, the demand for it isn’t that high, so manufacturers are not exactly interested in making many wool flannel sheets. In fact, those of you that want to benefit from wool as part of the bedding experience, are better off choosing wool blankets or duvet covers.
- If you ever come across “micro flannel” sheets, know that they are made with synthetic fibers. That shouldn’t bring you down (as we know that most people associate synthetic fibers with lower quality products) because polyester fibers can have quite a tight weave and be both durable and soft. However, those of you that use bed sheets made from natural fibers, such as cotton or silk, will surely be able to tell the difference between those and polyester flannel.
- Cotton and polyester blend flannel sheets are also a common and quite viable choice. When these two types of fibers are combined, you get the best of both worlds, which is the durability of polyester materials and the soft experience of cotton.
Benefits of Flannel Sheets
If you’re not sure whether or not flannel sheets are a purchase you want to make, let’s look at the four main benefits of choosing these products:
- The material is very soft considering the brushing process it has to go through. There are plenty of flannel sheets out there that are brushed on one or both sides, so it’s your decision which one you want to go for. Because of their softness, they are a really good choice for people with sensitive skin.
- They also have really good insulating properties, which is what propelled them to one of the top choices for fall and winter seasons. Since they have a brushed surface, they are really good at retaining heat, so the warm sleep pocket created between a top and a fitted flannel sheet is ideal for cold winter nights.
- Even though they have really good insulating properties, flannel sheets are also pretty breathable, which is a benefit that people don’t usually expect to get from warm bed sheets. If you opt for flannel sheets made from natural fibers, they are really good at wicking away moisture and serve even for warm sleepers that often feel thermal discomfort.
- Flannel sheets are created with a tight weave, which makes them pretty durable and is a good investment for those of you who are particularly interested in spending money on long-lasting products. When you care for them properly, flannel sheets can last for years to come.
How to Care for Flannel Sheets
A great part of making sure your sheets last for a long time is to know how to properly care for them. With flannel sheets, it really depends on the exact type of fibers used to make them. For instance, if you have wool flannel, then you will most likely have to dry clean your sheets (unless the manufacturer specifies otherwise). Synthetic sheets are the most low-maintenance ones of all.
There are plenty of experts that suggest you add half a cup of white vinegar the first time you wash new flannel sheets because they help set the dye into the fabric and will prevent pilling in the future. Flannel sheets should not be used with fabric softener because it makes the fabrics stiff in time.
It is never advised to wash flannel sheets in hot water, regardless of the fibers they are made from. You can air them to dry but it takes a long time (even though this drying method increases the durability of the sheets), but you can also use a dryer set at a low temperature.

Bottom Line
Dating back to the 1500s, flannel is a Scottish-made fabric that offers a soft and warm sleeping experience. While most people choose flannel for cold winter nights, quality flannel sheets are viable for usage throughout the entire year. The tight weave makes flannel sheets durable, while the napping method increases their softness. They are usually made from cotton, wool, or synthetic fibers, which means that aside from the benefits that flannel offers, you also get the advantages of the fibers that are actually being used to make the sheets.
