Irish sweaters: the surprising truth about their wool

Instead of finding its way into traditional knitwear, a lot of Irish wool ends up being exported to Britain and Europe where it is processed and used in various products, from carpets to upholstery. Wool for Aran sweaters and other Irish jumpers is often sourced from countries such as New Zealand or Australia, where the finer Merino wool is prized for its softness

Dr Michelle McKeown: "Wool is a natural, biodegradable material, which makes it an excellent choice for those looking to reduce their reliance on synthetic fibres. Unlike polyester or acrylic, which are derived from fossil fuels and contribute to microplastic pollution, wool breaks down naturally at the end of its life cycle."

The iconic Irish woolly jumper is known for its warmth, intricate patterns, and deep connection to Irish heritage. But there’s a twist in the yarn — most Irish jumpers aren’t made from Irish wool.

It’s a curious paradox. Ireland, with its rolling green fields and sheep-dotted hills, seems like the perfect place for a thriving wool industry. And it’s true that Irish sheep produce plenty of wool, but instead of finding its way into traditional knitwear, most of the Irish wool ends up being exported to Britain and Europe. Here it is processed and used in various products, from carpets to upholstery.
