Technologies

Down 700

Down is the best insulator we have. Its warmth to weight ratio, compressibility, longevity and softness are unmatched by artificial insulations. For all expeditions, duck down is a great choice for warm clothing and equipment.

Down Codex

DOWN CODEX is a multi-awarded certification scheme that considers environmental, ethical and animal welfare issues in relation to downstream supply chains. It is based on a comprehensive and transparent audit that ensures traceability and quality.

Drill the Loft

Drilite Loft is an exclusive range of highly water repellent fabrics used in insulating clothing and equipment. Introduced nearly 30 years ago, the original Drilite Loft was years ahead of its time: a highly breathable, lightweight and highly water-repellent fabric. These three hallmarks continue with modern Drilite Loft fabrics.
