Let's Not Waste Swedish Wool

The Belay Series is Made out of Swedish Wool and Waste from Sugar Production

We strive to always be at the forefront of sustainability and functionality. The Belay Series is a range of lightweight insulation garments that combine the highest functionality for serious mountaineering with making use of Swedish wool that up until now has been regarded as waste, and waste from sugar production. Around 60% of the garment is made out of renewable material and waste products from other industries.

The Belay Series is a range of lightweight, warming and durable insulation garments with a long lifetime. In this type of garments the filling is usually made out of synthetics or down, but the advantages with wool are many. The wool padding is lightweight, holds the ability to absorb and transport moist and to regulate your body temperature. This makes the garments ideal both for mountaineering and life in the city. The fabric is a lightweight, quick drying, durable ripstop polyester that is both wind and weather proof.

More than 800 tons of wool goes to waste in Sweden every year

Wool is a natural and renewable material. The majority of the wool that is produced in Sweden is rejected and dug into the soil. We wanted to make use of the Swedish wool and started a collaboration with Ullkontoret at Gotland and lavalan. Together we find and collect the wool that would otherwise be thrown away, and transform it to highly functional insulation. The advantages of Swedish wool are many; reduced transports, good conditions for the sheep thanks to strong Swedish animal welfare laws and we make use of an already produced product that otherwise would have been wasted. The result is a 100% renewable padding.

Waste from sugar production becomes polyester

Polyester is a durable material with great breathability but for many years we’ve been working to reduce the use of fossil material. Together with a Japanese weaver, we have developed a thin and durable polyester where the molekyl partially is built of waste products from sugar production. The longtime plan is a polyester where 100% is built of renewable resources, which has now been made in laboratories. Our goal is to implement this material in 2023.

When we started the development of the Belay Series, we decided to challenge ourselves and see how fossil free we could make these garments. The result is that around 60% of a Belay garment is made out of renewable material.

Report from the mountain guides

The Tierra Test Team used the Belay garments during the winter season 2018/19. The Tierra Test Team consists of experienced mountain guides and other extreme users. They experienced that you didn’t need to take on and off the jacket as often as with a synthetic insulation jacket. They were also surprised by the light weight of the garments.

Wool Facts & Figures

In Sweden, about 1 200 tons of raw wool is produced every year. More than two thirds of the wool, more than 800 tons, is thrown away. Out of the wool that is taken care of, more than half is exported to Great Britain among others.

219 tons of raw wool, worthy of 10,3 millions SEK, was imported to Sweden in 2017. Most of this wool was imported from New Zeeland.

Ullkontoret at Gotland is the only large scale wool souring mill in Sweden. The cost of scouring is four times bigger in Sweden than in Belgium, including transports to Sweden.
