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.

100% organic cotton



The Boll & Branch Flannel Sheets are a high quality take on the cotton flannel design. Woven in Portugal, these sheets are made of 100% organic cotton, which makes for a more breathable style of flannel that still retains its warmth.

The brushed, velvety finish of these sheets not only makes them soft to the touch, but also helps reduce wear and pilling, which can be a problem for flannel sheets in general. The sheets have been certified by the Global Organic Textile Standard (GOLS), which is the industry standard for organic certifications.

Boll & Branch Sheets are produced using fair wages and minimizing water usage, making these a good choice for those who value humanity and sustainability.

The Boll & Branch Flannel Sheets come in four distinct neutral colors and seven standard sizes. The set includes a flat sheet, fitted sheet, and 1-2 standard or king pillowcases depending on the size you get. Boll & Branch also offers free returns for up to 30 days.




100% cotton



Cotton flannel is a popular bedding material because it sleeps cool during hotter times of the year but also insulates against the cold when temperatures dip. The Standard Textile Flannel Sheet Set takes comfort a step further by using brushed cotton, an exceptionally smooth material with a soft hand-feel that is optimal for people with sensitive skin. This set has also earned the OEKO-TEX Standard 100 certification, meaning the sheets and pillowcases do not contain any harmful chemicals.

Customers can choose from four solid colors, as well as two attractive check designs. Six sizes ranging from twin to king and California king are also available. The fitted sheet is compatible with mattresses measuring up to 16 inches thick, which comprises the majority of models sold today. Each item can be laundered in your household washer and dryer, making the set easy and cheap to clean. You can choose from six solid colors and two check patterns for your sheets.

The price-point for the Flannel Sheet Set is very approachable and Standard Textile will ship for free anywhere in the contiguous U.S. Returns are accepted within 90 days of your original purchase, even if you’ve slept on or cleaned any of the items.




100% long-staple cotton



Saatva’s reputation for high-end sleep products extends well beyond the brand’s mattress line. Take the Luxury Flannel Sheet Set, which consists of sheets and pillowcases crafted from durable long-staple cotton. Each item is brushed during production to create an exceptionally soft finish that adds to the cozy feel. The cotton’s superior insulation is ideal if you run cold in bed, or your local climate veers toward chilly conditions during the fall, winter, and early spring months.

You can choose from two neutral colors, slate or sand. The set is also available in seven sizes, including a split king for couples who share an adjustable bed in this size — you’ll get two fitted sheets with these orders. A pocket depth of 16 inches makes the set compatible with most mattresses made today, including many high-profile models that are too tall for standard-pocket sheets.

All of the set’s components are fully machine-washable for quick, convenient care. Simply wash in cold water with similar colors, then tumble dry on low heat. Do not use bleach, as this can cause the colors to fade. The sheets and pillowcases should gradually soften over time and feel more lived-in.

The Luxury Flannel Sheet Set is fairly expensive compared to the competition, but Saatva offers free ground shipping for all orders and a 45-night trial for testing out the bedding in your own home. If you decide to keep the set, your purchase is further backed by a one-year warranty against manufacturing defects.




100% Cotton



Woven in Portugal, the LL Bean Ultrasoft Comfort Flannel Sheet Set is available in a generous range of bright earthy tones such as driftwood, mineral green, and silver sage. The breathable sheets are made of 100 percent cotton and have a medium weight that makes them suitable for use in summer as well as in winter.

Together with the team in Portugal, LL Bean has developed a way to remove excess fibers in order to give the sheets a smoother feel. The result is a set of hardy, pill-resistant sheets that keep their color and softness over time, even with repeated washing. The sheets are available in twin, full, queen, or king sizes and hold OEKO-TEX Standard 100 certification.

During the first year, if you decide the sheets aren’t for you, you can send them in for a full refund. After this time, LL Bean will only accept returns of sheets that present defects in materials or workmanship.




100% cotton



Most flannel sheets are relatively soft, but the Ultra-Cozy Cotton Flannel Sheet Set from The Company Store stands out from the competition thanks to each item’s velvety finish. A brushing technique applied during production not only makes the sheets and pillowcases feel exceptionally comfy and cozy, but also helps the cotton resist pilling and other forms of wear and tear.

Five sizes are available. Twin and twin XL sets include a flat sheet, fitted sheet, and pillowcase, while full, queen, and king sets feature all of these components as well as a second pillowcase. You can also choose from 12 different colors. Your options include classic neutrals like white and cream, as well as more striking shades such as merlot, forest green, and teal.

The fitted sheet has a pocket depth of 16 inches, so you can use the set with most mattresses made today. To launder the sheets, machine-wash in cold water on a gentle cycle with like colors and tumble dry on low heat. Following the care instructions is the best way to retain the original color palette.

The Ultra-Cozy Flannel Sheet Set is reasonably priced and all orders within the contiguous U.S. qualify for free ground shipping. The Company Store’s trial and return period runs for 30 nights after the delivery date.




100% cotton flannel



Many people appreciate flannel sheets for their exceptional softness, but uncomfortable heat retention is a common complaint about this type of bedding. During our hands-on tests, we found that the Brooklinen Flannel Core Sheet Set sleeps fairly cool compared to the competition. Each item in the collection is composed of cotton flannel that has been brushed, a process that relaxes the fibers and makes the fabric luxuriously soft. Cotton’s natural breathability also helps reduce heat buildup on warm or humid nights without sacrificing insulation during chillier times of the year.

The set is available in five sizes that correspond with standard mattress dimensions. Twin sets include a flat sheet, fitted sheet, and single pillowcase, while larger sizes feature all of these elements as well as a second pillowcase.

To launder your bedding, wash in cold water and tumble dry on low heat.

If you’re looking for a larger collection, Brooklinen also offers the Hardcore Bundle. This set includes all four Classic Core items along with two extra pillowcases for a total of four and a duvet cover. You can also purchase these items individually in patterns that match your Classic Core set.

Brooklinen’s 365-night sleep trial is one of the longest in the online bedding industry, ensuring plenty of time to test the sheets and decide whether they’re right for you. Returns are accepted for all purchases during this time frame, even if you’ve used and laundered your bedding. If you decide to keep the Flannel Classic Core Sheet Set, you’ll receive an additional year of warranty coverage against material defects.

100% long-staple organic cotton



Comfort is a hard quality to gauge for sheets because everyone’s tastes are subjective. That said, most members of our testing team agreed the Brushed Flannel Sheet Set from SOL Organics felt soft, smooth, and cozy without trapping too much heat. Shoppers can currently purchase this collection in a bundle with additional bedding items.

Each component in the set is composed of long-staple cotton, a material prized for its longevity and natural cooling properties. Since the cotton fibers are brushed during production, the finished product is remarkably easy on your skin — a benefit for people with conditions like acne and eczema.

What is Flannel?

The origins of flannel are thought to date back to 16th-century Wales, where it was made using carded (untangled) sheep’s wool. This heavy, smoothed-out yarn was woven in a thick weave, usually twill or plain weave, and then almost always brushed, or napped. The method resulted in a durable fabric that was soft and warm, even getting softer over time.

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.

How to Choose Flannel Sheets

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.

What to Consider When Buying Flannel Sheets

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.

  • Material: Regardless of their weave, all sheets made of a certain material tend to have some common characteristics. Cotton is breathable, wool is warm and moisture-wicking, and polyester microfiber is wrinkle- and stain-resistant. Flannel sheets can be made of any of these fibers, but most people find that cotton flannel provides a happy medium between warmth, softness, and breathability.
  • Weave: Common sheet fabrics such as percale or sateen are defined by their weave, which plays an important role in determining the feel and properties of the sheets. In contrast, flannel can be made of any of a number of weaves, most often twill weave or plain weave. The principal factor that makes it flannel is that it be woven in a way that confers warmth without sacrificing breathability.
  • Feel: The feel of a sheet set is most affected by the material and the way it’s woven together. Flannel gets its “fuzzy” feel from being napped, a technique in which the fabric is brushed after it’s woven. Flannel sheets can be napped on both sides or just one side, and the napping can be heavy or light. Sheets with a long nap on both sides are usually the softest and warmest, as the nap traps more warm air.
  • Fit: While most bedsheet sets are tailored to fit the standard mattress sizes, it pays to double-check because not all manufacturers sell their sheets in all sizes. Additionally, mattresses with a higher-than-average profile may require deep-pocket fitted sheets. As with other types of cotton sheets, cotton flannel often shrinks the first time it is washed. Many manufacturers pre-shrink their sheets or make them a little bigger to compensate for this.
  • Price: Sheets come in every budget, starting at around $20 and reaching into the hundreds for luxury sheet sets. The price of your flannel sheets will depend on what material they’re made of, whether they are organic and ethically made, and how they’ve been treated – whether double-napped, sheared, brushed, etc. You can usually expect to pay between $100 and $200 for a good flannel sheet set.
  • Weight: Unlike other types of sheets, flannel sheets are measured by weight instead of thread count. Described in grams per square meter (GSM), the weight gives you an indication of the durability and warmth of the sheets. Heavier sheets (around 170 gsm) are usually more durable and retain more warmth, while lightweight sheets (around 135 gsm) will sleep cooler. Of course, this also depends on other factors such as what material the sheets are made of.
  • Design, Color and Pattern: We all want our sheets to match our bedroom, and the good news for flannel lovers is that flannel comes in limitless designs, from the traditional plaid to solid colors and other prints. That said, the colors on offer may be limited depending on the type of flannel.
  • Breathability: The breathability of your sheets mostly depends on how loosely they are woven and the quality of the fibers. Loose-woven fabrics or long-staple fibers tend to allow more room for air to pass through. The fabric itself also plays a role. Wool is hands-down the most breathable type of flannel due to its ability to wick moisture away from your body. Cotton is also quite breathable, while some synthetic materials may have you waking up in a pool of sweat.
  • Durability: Compared to other types of sheets, flannel sheets are fairly durable and don’t normally tear as easily. However, because of its brushed fibers, flannel can be vulnerable to pilling. Some manufacturers recommend adding vinegar to the first wash cycle to enhance their durability and keep the fabric soft.
  • Ease of Care: Ease of care is especially important for bed sheets, which need to be washed regularly. Care instructions for flannel sheets vary according to the material, but most can be machine washed in cold or warm water, and dried on low heat or line-dried.

What Types of Flannel Sheets are Available?

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.

  • Cotton: Cotton flannel is soft and lightweight, making it a common choice for bed sheets. Cotton flannel bed sheets will perform differently depending on the cotton staple and the tightness of the weave, so it’s smart practice to check these details before purchasing. Low-quality cotton sheets are known to pill quite easily and have a shorter lifespan.
  • Wool: Wool is the original flannel material, and arguably still the best. Known for its unbeatable moisture-wicking properties, good-quality wool is warm, lightweight, strong, and practically dry to the touch even when it’s full of moisture. Unfortunately, it’s also one of the more expensive materials, and is hard to find in sheets, being more often used in blankets and mattress comfort layers.
  • Synthetic: Synthetic flannel, usually made from polyester microfiber, is stain- and wrinkle-resistant, durable, and easy on the wallet. However, it may not feel as soft and luxurious as flannel made from natural fibers, and it’s often treated with flame-retardant chemicals to reduce its natural flammability.
  • Blend: Some flannel manufacturers blend cotton and polyester in an effort to reap the benefits of both. Blended flannel can be softer and warmer than polyester flannel, and more resistant than cotton flannel. The addition of synthetic fabrics can also help reduce wrinkling and stretching.

What are the Pros and Cons of Flannel Sheets?

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.

  • Warm: Flannel sheets can be either lightweight or heavyweight, but both will keep you warmer than equivalent sheets in another weave, especially if napped on both sides. It may even keep you warm enough to avoid using a blanket in the shoulder season.
  • Soft: The raised fibers have a fuzzy feel that many people associate with snuggling up in bed during the long winter months. For maximum softness, look for sheets that are napped on both sides.
  • Breathable: Wool flannel is the most breathable type given the natural moisture-wicking properties of wool. However, cotton flannel and lightweight micro flannel can also be relatively breathable.
  • Durable: Flannel requires a bit of special attention, but if properly cared for, it can be one of the more durable fabrics.
  • Prone to pilling: Flannel pills more easily than other types of sheets due to its exposed fiber ends. Using care when washing and drying can help reduce pilling and prolong the longevity of your flannel sheets.
  • Don’t sleep cool: Most people buy flannel to keep warm, and although lightweight flannel is fairly breathable, it still traps some heat. If you’re a hot sleeper, a better choice would be a breathable weave such as percale.

Who is Best Suited to Flannel Sheets?

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.

What is the Ideal Weight for Flannel Sheets?

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.

Frequently Asked Questions

What is the typical price range for flannel sheets?

Synthetic flannel sheets start in the $20 to $30 price range, with cotton flannel coming in between $50 and $150, and wool costing significantly more. The price can vary depending on quality, country of  origin, and other factors.

How long do flannel sheets last?

Like other good-quality sheets, flannel sheets can last for years if properly cared for. Of all vices, flannel sheets are most vulnerable to pilling, especially if washed in too-high temperatures or mixed with zippers or synthetic fabrics in the machine. This doesn’t mean you should refrain from washing your flannel sheets regularly – quite the opposite. Just be careful to follow the care instructions to the letter to avoid premature pilling.

How do I wash and care for flannel sheets?

Synthetic and cotton flannel can usually be machine-washed and dried on low temperatures, while wool flannel may require dry-cleaning. Most manufacturers recommend avoiding fabric softeners and bleach, and using less than the recommended amount of detergent to prevent product residue. To avoid pilling of the exposed fiber ends, some also recommend adding vinegar the first time you wash your napped flannel sheets. Taking the sheets out of the dryer before they’re completely dry may help reduce wrinkles. Always follow manufacturer instructions to get the best results, and don’t be scared if you see lint in the dryer the first few times you dry the sheets. This is a natural by-product of the napping process.

What is napping, and why do I want it on both sides of my flannel sheets?

Napping refers to the practice of brushing the fiber ends with a metal tool, raising them to create small air pockets which insulate against the cold. Most flannel is napped on at least one side, and many sheets are “double-napped,” or napped on both sides, to increase their warmth and softness. The length of the nap will also affect the feel, and higher-end sheets may be sheared after the napping process to make them even smoother.

Where do the best flannel sheets come from?

Portugal is most reputed for the quality of its flannel, due to a combination of expert craftsmanship and high-quality long-staple cotton. Germany is a close second, and England is not far behind.
