This trekking collection was created so that nothing surprises you in the mountains. Each layer has its task here – from breathable merino bases, through Primaloft and Polartec insulation, to coverings with a hydrophobic coating. They combine into a set that gives you the freedom to choose – exactly as many layers as you need at any given moment.
A distinctive colour palette inspired by the trail at sunrise and sunset not only emphasizes the character of the collection but also increases visibility in the field.
This is a collection that works in the rhythm of your march. It proves itself where the beaten paths end – and the real adventure begins.
