Nature’s very own functional material

We love wool here at Fjällräven. It’s arguably one of nature’s most functional materials. And you’re most likely aware of its ability to keep you warm by trapping air between its fibres. But did you know that, strictly speaking, wool isn’t an insulator? It’s a heat regulator. This is because it can help you keep your cool as well as keep you warm and cosy.

Wool wicks away moisture from your body. And when it does so, it takes odours with it. So even though you may spend all day trekking and working up a sweat, your wool clothing will hardly smell at all.

Finally, because of the structure of the fibres, wool keeps you warm even when it’s damp. And depending on the size of the fibres, wool clothing can be really thin, not to mention durable and comfortable.

We use lots of different types of wool, including spill or surplus wool from our suppliers in Italy and wool sourced from sheep in Sweden. This is all to reduce our environmental impact. You can read more about how we work with sustainable materials here.

Ethically sourced, fully traceable


We’ve had fully traceable, ethically-sourced down in our products since 2014. In 2015 we started looking into how we could achieve the same in our wool chain too. Due to the way wool is commonly traded, it’s been extremely difficult to develop a fully-traceable global wool supply chain. But things are changing.
