Flannel Jackets for Men

Flannel gets associated with casual shirts, but as a jacket fabric it sits in a different league entirely. Flannel wool is brushed after weaving to raise a soft nap that insulates, absorbs sound and drapes with a weight that sharper worsteds cannot match. The result is a jacket that feels substantial without stiffness — warm enough for cold offices and winter commutes, soft enough to wear all day without fatigue. Off-the-rack flannel jackets rarely fit well because the fabric's thickness exaggerates any sizing error. At Hockerty every flannel jacket is cut to your measurements so the weight hangs where it should, the shoulders sit clean and the chest lies flat. Choose from gray, navy, charcoal and earth-tone flannels in weights from 280 to 370 g/m. Pick your lapel, pocket style, buttons and lining. Delivery in about 4 weeks, free shipping and a Perfect Fit Guarantee covering any alterations needed.

What makes flannel different from regular wool suiting?

Standard worsted wool has a smooth, crisp finish. Flannel is brushed after weaving to raise tiny fibers on the surface, creating a soft nap that feels warmer to the touch and drapes more loosely. This brushing also gives flannel its matte appearance, which reads less formal and more textured than a polished worsted.

Is a flannel jacket too casual for the office?

Not at all. Gray flannel jackets have been an office staple for decades. The fabric looks refined without being overly sharp, which suits smart-casual and business-casual dress codes perfectly. Pair it with a cotton shirt and wool trousers for a classic look that works from meetings to after-work drinks.

Will flannel pill over time?

The brushed surface can develop some pilling with friction, especially around the cuffs and where a bag strap sits. Regular brushing with a garment brush removes pills before they build up. Higher-quality flannel with longer wool fibers pills less, and any early pilling usually stabilizes after the first few wears.

What seasons suit a flannel jacket best?

Flannel excels from mid-autumn through early spring. The brushed nap traps air for warmth, making it comfortable in cold offices and during winter commutes. In lighter weights around 280 g/m it can stretch into cool spring evenings. For summer, flannel is too warm — switch to linen or tropical wool when temperatures rise.
