The Expedition 8000 salopettes are our warmest insulated pants built for the most extreme conditions, whether you're summiting an 8,000m peak or crossing the polar ice caps. Filled with 850 FP goose down and built with robust and weather resistant Pertex® Quantum Pro outer fabric, these salopettes have been developed to retain heat in the world’s coldest environments.

A downproof Pertex® Quantum lining and boxwall baffle construction with differential cut maximise loft to improve heat retention. The chest and cuffs are filled with synthetic PrimaLoft® Gold insulation, with a spacious kangaroo front pocket for storing frequently used items.

Providing protection from harsh conditions, the salopettes have space to accommodate bulky layers and the knees have been optimised for articulation to enable freedom of movement on challenging terrain. Featuring an extended length two-way front zip (ideal for relief), adjustable support braces, full length side vents and mitt friendly oversized features, these salopettes have been refined to cope with the demands of expeditions.

Pertex® Quantum Pro Fabric

Pertex® Quantum Pro uses an ultra-thin water-resistant coating to provide increased protection in rough conditions. By combining a tightly woven face fabric with a microporous coating, Pertex® Quantum Pro delivers weather resistance whilst remaining lightweight, soft, and breathable. It’s ideal for use in cold or damp environments.
