Our Belay collection is the result of our strive to always be at the forefront of sustainability and technology. With a unique combination of partially biobased polyester fabrics and 100% renewable wool padding, we continue the path we started two years ago with Deterra towards a fossil-free and renewable future.

Lavalan® wool is a technically advanced wool insulation made from 100% natural raw materials. Wool buffers temperature and moisture, providing cozy, comfortable warmth, individually adapted to respective weather conditions and activity levels. Since wool is thermoregulating it also provides a cooling effect and prevents you from overheating even during high-intensity exercise or unexpected warm weather. 

The wool we use for the Belay series- “Lavalan – Swedish wool”, is collected on the Swedish island of Gotland. Until now most wool produced/sheered in Sweden is being regarded as waste and is dug down in the soil. Together with Ullkontoret and Lavalan we find and collect the wool that would otherwise be thrown away, and transform it into highly functional and ecological insulation (https://www.lavalan.de/). The lightweight and ability to regulate temperature make the garments ideal for upbeat adventures in the mountains as well as calmer activities in the city.
