About this brand

Kjus is the epitome of Swiss precision with a racy piste look. Lasse Kjus himself was the most medalled Norwegian ski racer of all time and the only person to win a medal in all five alpine disciplines at a single Championship. The first KJUS collection was launched in 2000 with Swiss entrepreneur Didi Serena. The Speed Reader jacket is in honour of Kjus’ accomplishments. The collection is tailored to an exacting fit without sacrificing performance. This is a collection that uses the latest technical fabrics that offers classic style and freedom of movement whether you’re charging hard or cruising corduroy. Kjus develop their own fabrics in Japan. Their product development takes around 2.5 years from sketch to store.
