Handcrafted Irish Flat Caps From the Heart of Ireland

Of all the Irish hats, there’s a special place in our hearts for the flat cap. It’s an icon of Irish heritage, traditionally made from wool or tweed and worn across Ireland for generations by farmers, fishermen, and city folk alike.

These caps are warm in winter, breathable in summer, and durable enough to last decades. But aside from the practicality, it’s the character these hats have that stands out. The soft peak, the subtle curve, and the distinctive tweed patterns make it instantly recognisable around the world.

Aran Sweater Market is honoured to continue this tradition. We’ve spent decades celebrating Irish craftsmanship and our caps are no exception. Each is made in Ireland by expert makers using authentic Donegal and Kerry tweed, woven from natural fibres that balance comfort and longevity.

Whether you choose a herringbone, plaid, or solid weave, every piece reflects the same dedication to quality that defines all our collections. Here’s what separates our Irish flat caps from the imitators online:

Authentic Irish origin: Every cap is produced in Ireland, supporting local weavers and preserving traditional craft methods.

Premium materials: We use 100% wool tweed and wool blends for comfort, structure, and durability. These materials will last a lifetime with proper care.

Attention to detail: Many designs have quilted linings, classic peaks, and tailored shaping for a perfect fit that you’ll love to wear.

Timeless design: Our caps blend historic Irish charm with modern versatility. They’re a natural fit for both everyday wear and formal occasions.

Frequently asked questions

What are Irish flat hats called?

They’re most often called Irish flat caps or tweed caps, though some people refer to them as newsboy caps or Paddy caps. The “flat” design and short, curved brim is truly one-of-a-kind.

Why do the Irish wear flat caps?

They were originally made for everyday working people who needed warmth and durability. But over time, they earned a place in Irish identity. Today, they’re worn by men and women alike as timeless fashion pieces.

How should an Irish flat cap fit?

A proper Irish flat cap should sit snugly on your head without feeling tight. It should rest just above your ears and the brim should frame your forehead comfortably, giving you plenty of room for breathability and movement.

Are flat caps classy?

Absolutely! They carry an understated sophistication that works across generations. Whether paired with a coat and scarf or jeans and a sweater, they bring a sense of polish without being overly formal.
