For many people, flannel is a quintessential part of winter. Most commonly made of wool, cotton, or polyester, flannel has a characteristically fuzzy feel that comes from brushing out the fibers after the fabric is woven. This adds an extra layer of coziness and makes flannel sheets a beloved choice by sleepers looking to stay warm through the night.
Whether you plan to use flannel sheets to save on your heating bills or whether you just like the feel, we’re here to help, with a comprehensive guide to flannel sheets and a list of our top picks. All of our choices are 100 percent cotton flannel, which provides the best balance of softness and durability.

Slumber Cloud is a bedding company that offers a line of sheet sets, each with varying degrees of warmth and coolness. The Flannel Sheet Set is the brand’s warmest sheet option, but the company uses a patented fabric that helps control temperature and makes the sheets more comfortable for sleepers who run hot.
The Slumber Cloud Flannel Sheet Set is made with a blend of 60% cotton and 40% Outlast viscose. These patented fibers are designed to store heat from the body as it warms up and release heat as your body cools down. This allows the sheets to confer warmth without necessarily overheating the body. Although the sheets are designed to reduce overheating, the flannel material will likely still be too hot for people who run hot.
Since the fabric technology responds to an individual’s body temperature, the Slumber Cloud Flannel Sheet Set is able to provide customized temperature regulation for couples who share a bed but have differing thermal preferences.
These Slumber Cloud sheets have a brushed finish and provide the soft feel that people commonly associate with flannel. The set is available in one color (gray), and the six size options are twin, twin XL, full, queen, king, and California king. Fitted sheets have a pocket depth of 15 inches, but the elastic construction allows them to fit mattresses up to 18 inches thick. The sheets have OEKO-TEX Standard 100 certification to ensure that they do not contain harmful chemicals.
Customers receive a 60-day trial and may return the sheets for a full refund within this time period. Return shipping is free. The sheets are backed by a 180-day warranty.

Flannel spread to the U.S. in the 1800’s, where it played an important role in protecting chilly workers in trades such as railway construction and logging. Throughout the 20th century, flannel was used by a wealth of wide-ranging populations including the army, the working class, outdoor enthusiasts, and the Seattle grunge movement. The fabric eventually spread to the mainstream, and the plaid flannel shirt is now considered a staple in the American wardrobe.
No longer relegated to freezing outdoor jobs, cozy flannel is now a popular choice for winter bed sheets and pajamas. Today’s flannel sheets come in a diverse range of materials, including cotton and microfiber.
Flannel is a fairly general term, and flannel sheets vary widely in quality and feel depending on factors like their weight and what material they’re made from. We’ll dive into how flannel sheets are made and what to look for when buying to help you can narrow down your choices.
We’ve made a list of the most important things to keep in mind when buying bed sheets. Some of these are inherent to every type of bed sheet, while others more specifically apply to flannel. Luxury prices aren’t always a promise of higher-quality materials, but with a better understanding of these factors you’ll be able to see past the marketing jargon and hone in on the best bang for your buck.
Originally made from wool, flannel has since branched out and can now be found in a variety of materials. While all flannel sheets share broad advantages, such as their insulating ability, each material brings its own additional benefits and drawbacks.
Soft and fuzzy flannel is a favorite with many people, especially in winter. However, hot sleepers may not be so enthusiastic about its warm and cozy feel. Here are some of the main pros and cons of flannel.
Flannel sheets are primarily chosen for their cozy feel and ability to keep sleepers warm. They’re often used as a supplement to a heavier comforter or duvet, and can even suffice on their own in moderately cool weather. Because flannel made from wool or cotton is also relatively breathable, some sleepers may opt to use lightweight flannel sheets year-round.
Despite their advantages, flannel sheets aren’t for everyone. Sleepers who tend to run hot or those who live in warm climates will likely find that flannel traps heat and makes for an uncomfortably warm night. Hot sleepers usually prefer breathable percale or linen sheets.
Flannel requires careful washing and drying to prevent pilling and wrinkling, which may be frustrating if you’re short on time. If this is a concern, synthetic flannel made from polyester or microfiber is the way to go.
Instead of using thread count like other types of sheets, flannel sheets are measured in grams per square meter (GSM). This describes the weight of the sheets, with implications for the material’s breathability and warmth. Of course, the materials used to make the flannel also have an impact on its durability and feel. Synthetic micro flannel sheets are usually more lightweight.
The most expensive flannel is heavyweight flannel, which weighs at least 170 gsm, or 5 ounces per square yard. Due to its tighter weave, heavyweight flannel is more durable and less likely to pill. It also traps more heat, which for many people is the aim of buying flannel sheets. That said, beware of sheets that are exceedingly heavy with coarse fibers, as this usually indicates poor-quality sheets.
By contrast, lightweight flannel refers to flannel that’s lighter than 135 gsm. This flannel is more breathable and retains less heat, but it’s likely to pill more easily and usually has a shorter lifespan. Flannel that lies between these two extremes may be the most suitable for those who plan to sleep with their flannel sheets all year long.
