Flannel is more than just a fabric—it’s a representation of social change, with a history that spans continents and centuries. Imagine the sweeping coastlines of 17th-century Wales, the overcast streets of 1990s Seattle, and the countless dresser drawers of people who have found comfort and confidence in a great flannel shirt.
Flannel’s innovation goes beyond technical achievement. It helped usher in evolving ideas of comfort, identity, and self-expression. In the 19th century, women’s rights activists wore men’s flannel shirts as an act of rebellion against restrictive Victorian clothes and male-imposed oppression. With its connections to women’s rights, political movements, and evolving ideas of gender, it’s no wonder that flannel has become a mainstay in queer fashion.
In this guide, we’ll explore what flannel really is (and isn’t), trace its rich history, and discover why it remains a wardrobe staple for so many of us.
Flannel vs. Plaid: What’s the Difference?
Flannel is not the same as plaid, though the two terms are often used interchangeably. Flannel is a type of fabric, and plaid is a pattern. Many flannel shirts feature plaid patterns, but not all plaid shirts are made from flannel, and not all flannel is plaid. It’s easy to see why people mix up flannel and plaid. Walk into any store or browse online, and you’ll spot flannel shirts in every color of plaid imaginable.
Retailers and pop culture have blended the two in our minds, but here’s the key: flannel is the fabric itself, while plaid is the pattern you see printed or woven onto it.
Flannel isn’t limited to one look. You’ll find it in solids, stripes, checks, and classic tartans. No matter the pattern, flannel is known for being soft, warm, and textured. Plaid, on the other hand, is a specific checkered pattern with roots in Scottish tartans—those traditional woven designs that once signified different clans.
Remember: flannel is the material, plaid is the pattern. You might own a plaid cotton shirt that isn’t flannel, a solid navy flannel shirt, or even a striped flannel. They’re often paired together, but they’re not the same, and now you know the difference.
What Is Flannel Made Of?
Flannel is all about softness, but it can be made from a variety of materials, each with its own unique benefits. A common misconception is that flannel can only be made from cotton. While many flannel shirts you’ll find today are made from cotton, flannel can also be crafted from wool, synthetics, or blends.
-
Cotton flannel is the go-to for shirts because it’s lightweight, breathable, and easy to care for.
-
Wool flannel is heavier and warmer, perfect for tailored pieces like blazers and trousers.
Then there’s synthetic flannel, made from polyester or other fibers, which you’ll often find in bedding, outdoor gear, or budget-friendly options thanks to its durability and quick-drying nature.
The Weaving and Brushing Process of Flannel
To achieve flannel’s signature coziness, it’s all about the weave and finishing. Flannel is woven loosely, which creates tiny air pockets that trap warmth while still letting your skin breathe, making it the perfect choice for colder weather.
Next, the fabric is brushed with a fine metal comb in a finishing process called napping. The comb lifts loose fiber ends, giving flannel that slightly fuzzy texture it’s known for.
Some flannel is single-brushed, with just one side treated for softness, resulting in better durability and structure. Double-brushed flannel means both sides are brushed, making it extra warm, though more prone to pilling.
Not every flannel is brushed, though. Some skip this step and still count as flannel, thanks to their weave.
Flannelette, though, isn’t a type of flannel at all. It’s a lightweight cotton fabric designed to mimic the feel of flannel, usually by brushing just one side.
The History of Flannel
Origins in Scotland and Wales
Flannel’s story starts in the misty fields of Wales and Scotland during the 17th and 18th centuries. Early flannel was crafted by carding wool, a process that combs the fibers to align them and remove impurities, resulting in a fabric that’s both soft and durable.
With plenty of sheep and skilled weavers, flannel quickly became a cold-weather staple. As the wool trade grew, flannel made its way from Wales and Scotland and eventually into European and American markets.
Flannel in America
The Industrial Revolution took flannel from a local favorite to a global staple. In America, flannel became the fabric of choice for miners, railroad workers, and farmers thanks to its warmth, durability, and ease of layering.
The legendary image of Paul Bunyan in his red plaid flannel shirt helped cement flannel as a symbol of the great outdoors and rugged masculinity, but its story was just beginning.
Flannel has always been open to reinvention. In the 1970s, Tennessee senator Lamar Alexander donned a red-and-black flannel shirt on the campaign trail, turning it into a symbol of connection with everyday people.
By the 1990s, flannel was everywhere. Bands like Nirvana and Pearl Jam made it the uniform of a new, rebellious youth culture. Kurt Cobain’s flannel shirts transformed the fabric from practical to aspirational, making it cool to be working class.
Flannel is a rare example of a fabric that went from subculture to mainstream and now transcends demographics. People of all ages, genders, and classes wear flannel.
Types of Flannel
Flannel isn’t one-size-fits-all. There are several types, each suited to different uses.
Cotton Flannel
The most common type of flannel. It’s used in shirts, pajamas, and bedding. Lightweight, soft, and breathable, it’s perfect for everyday wear.
Wool Flannel
Heavier and more insulating, wool flannel is traditional in tailored garments like blazers and trousers, especially in heritage British suiting.
Brushed Flannel
This refers to flannel that has been brushed on one or both sides for extra softness and warmth, whether it’s made from cotton or wool.
Double-Brushed Flannel
Both sides of the fabric are brushed, making it extra cozy—ideal for sheets, pajamas, and loungewear.
Flannelette
A thinner, brushed cotton fabric that feels like flannel but is lighter. Common in children’s clothing and pajamas.
