Flannel Fabric

Flannel is a soft woven fabric that has been brushed (napped) on one or both sides to create a fuzzy surface texture that traps warm air. Originating in 17th-century Wales (from the Welsh word "gwlanen" meaning woolen article), flannel was originally made from carded wool by Welsh farmers. Modern flannel is predominantly cotton or cotton-blend, though wool flannel remains the gold standard for tailoring.

The brushing process that defines flannel:

The napping process uses wire bristles to raise fiber ends from the woven surface, creating flannel's signature fuzzy texture. Fabric may be napped up to 6 times for maximum softness. Single-napped flannel (one side) is lighter and used for shirts; double-napped (both sides) is heavier and warmer for winter garments and blankets. Without napping, the same woven fabric would simply be called "cotton twill" or "plain weave."

Technical specifications:

• Weave: Both twill and plain weave constructions exist — twill flannel is more common in shirts, plain weave in baby flannel
• GSM range: 150–300 GSM (shirts: 150–200; heavy blankets: 250–300)
• Cotton flannel weight: 5–6.5+ oz/sq yd
• Wool flannel weight: 10–20 oz/sq yd (suiting range)

Types of flannel:

• Cotton flannel: The most common type — shirts, pajamas, casual wear. Available in plaid, solid, and printed
• Wool flannel: Heavier, used in suits, trousers, and blazers — a Savile Row staple since the 19th century
• Flannelette: Lighter-weight, cotton-only version with napping on one side only — common for baby clothes and light nightwear
• Baby flannel: Extra-soft, finely napped cotton for infant clothing and receiving blankets
• Flannel-backed satin: Smooth satin face with brushed flannel backing — used in premium bedding

Heritage brands and cultural significance:

• Pendleton (est. 1863, Portland, Oregon): Iconic plaid wool flannel shirts — an American heritage symbol
• L.L.Bean Scotch Plaid flannel shirt: Continuously sold for ~90 years — one of the longest-running products in American retail
• Woolrich Buffalo Check (est. 1850): The red-and-black buffalo plaid that became synonymous with American outdoors
• Filson (est. 1897, Seattle): Rugged flannel workwear for the Pacific Northwest
• Portuguese Flannel (Guimaraes, Portugal): 4th-generation family business producing premium cotton flannel — now a global cult brand
• Grunge movement (1990s): Kurt Cobain and Nirvana popularized flannel as countercultural fashion — thrift store flannel shirts became a generation's uniform
• Savile Row wool flannel: Grey flannel trousers remain the foundation of British menswear — the "flannel suit" defined mid-20th century office culture

Flannel is globally associated with plaid/check patterns, though it refers to the fabric construction, not the pattern. Plain, striped, and solid flannel fabrics are equally common in fashion.
