Big on performance. Small in your pack.

An outstanding warmth-to-weight ratio, ultralight and highly packable. Made from recycled polyester, it is the ideal companion for active days – whether on the move or in everyday life.

What makes it different

  • Weight

    At around 130 grams, the sweater is among the lightest in its class. You’ll barely notice it on your body – and it takes up virtually no space in your luggage.

  • Functionality

    The soft Alpha™ fabric keeps you warm while remaining breathable and quick-drying. Moisture is transported away from the body, while the Half-Zip allows you to easily regulate ventilation on the go.

  • Versatility

    The faluun sweater works as a warm mid-layer under a jacket or as a lightweight outer layer on milder days. Whether you’re hiking, cycling, camping, or simply going about your everyday life.

Made in Switzerland

Every sweater is sewn by hand in Thun, Switzerland. Made in small batches, with short supply chains and a strong focus on quality.
