Flannel is a woven fabric commonly made from polyester, cotton, or wool. The material is usually produced with a plain or twill weave, and has a characteristically fuzzy feel that comes from brushing the fibers.

The top and bottom are composed of flannel from Portuguese cotton, a material renowned for natural softness, and the fibers are brushed multiple times to enhance this quality. You can also choose from seven classic tartan patterns. The fabric is yarn-dyed, so the colors should remain bold and resist fading over time.

The two-piece set consists of a button-front top constructed for a loose fit, and slip-on bottoms with an elastic waist and drawstring closure. This pajama set offers a selection of five sizes ranging from extra small to extra large, as well as regular, petite, plus, and tall styles. A full size chart on L.L.Bean allows you to pinpoint which size will fit best. Optional monogramming is available for an extra fee.

You can wash and dry the pajamas in household machines for quick, easy care. The fabric may shrink a bit after the first laundry cycle, so you may want to consider a slightly oversized set. L.L.Bean allows customers to try out the Women’s Scotch Plaid Flannel Pajamas for up to one year before deciding whether to keep, return, or exchange them. This trial period is considerably long compared to other online pajama sellers.

What to Look for in Flannel Pajamas

Flannel pajamas are great for people seeking pajamas that feel warmer and cozier than traditional cotton or polyester sleepwear without trapping too much heat. If you’re in the market for new pajamas and considering a flannel set, there are a few qualities to look out for during your search. 


Flannel pajamas that keep you warm may help you sleep more soundly if you tend to wake up shivering and hugging your body during the night. High-quality flannel is warmer than other pajama materials, resulting in exceptional coziness and insulation. Most flannels insulate heat well, though heavyweight flannel pajamas generally provide the most warmth.

The more a flannel weighs, the warmer it feels. You may want to consider heavyweight flannel pajamas for winter months when temperatures are at their lowest — especially if your local climate can be extreme during this time — while a lightweight or midweight pajama set may be more comfortable for year-round use.


Natural wool typically produces the most breathable flannel pajamas. You may also benefit from wool flannel if you’re prone to night sweats, as this material has natural moisture-wicking properties. Cotton flannel is also fairly breathable, but does not provide as much moisture control. 

Flannels made from polyester offer minimal airflow. As a result, they may trap heat and cause you to sweat in your sleep. Silk is a great alternative for people who sleep hot and is often chosen for its breathability in warmer weather.


Anyone who enjoys soft, cozy sleepwear should find flannel pajamas comfortable. Flannel gets its softness from the brushing process after the fabric is woven. 

Wool flannels tend to feel “fuzzier” than other flannels. If you dislike this texture, we recommend cotton flannels, as they usually feel smoother than their wool counterparts.

Patterns & Dyes

Traditional flannels feature tartan plaid or check patterns. Pajamas with these designs carry a classic heritage look complete like notch collars and bias-cut detailing. There are also plenty of flannel pajamas available in other prints and solid colors.

If the flannel is yarn-dyed, the colors won’t fade as quickly in the wash. However, all flannel patterns eventually fade over time. You can preserve bold colors by laundering your pajamas on a semi-frequent basis and using cold water and gentle detergent.

Inclusive Sizing

Most flannel pajamas are available in multiple sizes. These include options for different body types, usually ranging from extra small to extra large, as well as regular, petite, and tall sizes. Many pajama sellers also offer designs specifically designed for men and women, with the latter sized slightly smaller.

Be sure to consult size charts when available. These charts can help you narrow down which sizes will fit best. Also keep in mind that flannel pajamas are likely to shrink a bit, so you may want to consider a larger-than-normal size, especially if you prefer a looser fit.

What Is Flannel?

Flannel is a fabric that is woven and brushed to create a soft, cozy feel that provides excellent warmth and insulation. Traditional flannel from the British Isles, which dates back centuries, is produced using sheep’s wool. Some modern flannels are still made from wool, but other materials such as polyester and cotton are more frequently used nowadays.

Brushing is what sets flannel apart from other textiles. This process relaxes the fibers, resulting in the signature “fuzzy” texture many associate with flannel. Many manufacturers brush their flannel multiple times to achieve as soft a feel as possible. Flannels are usually produced with plain or twill weaves.

Who Are Flannel Pajamas Good For?

Flannel pajamas are best suited to people who prefer feeling warm and cozy in bed. Many need extra insulation to sleep comfortably when nighttime temperatures are low, but some people prefer the added warmth throughout the year. 

Traditional flannel pajamas consist of long-sleeve, button-front shirts and pants with drawstring or button closures. These garments are often designed for a loose fit. If this sounds too bulky, flannel sleep shorts are also widely available. 

If you prefer sleeping with minimal clothing or no clothing at all, flannel pajamas may feel too warm, but you could consider flannel sheets to get the benefit of the warmth without the constricting feeling of clothing.

How Much Do Flannel Pajamas Cost?

Most flannel pajama sets cost $40 to $100. High-end flannel pajamas may cost more, but you can also find many budget-friendly pajama sets below $40. 

Expect to pay more for flannel pajamas made from high-end materials such as organic or long-staple cotton, merino wool, or cashmere. At the other end of the spectrum, polyester flannel sleep clothes tend to be the most affordable options. Prices also vary by seller, and established brands may charge higher prices than lesser-known competitors.

Flannel vs. Fleece Pajamas

Flannel is a woven fabric usually made from natural fibers such as wool or cotton. Fleece, on the other hand, is knit using synthetic materials like polyester. Fleece also has a thicker pile, so it feels plusher to the touch. Generally speaking, fleece sleeps warmer than flannel but traps more heat, making it less suited to sleeping on warm nights. Flannel is a better choice if you’re looking for pajamas you can use throughout the year.
