Expedition Windsuit

Our expedition gear is built for use in the world’s most extreme environments. We use cutting edge materials and innovative designs, informed by the experiences of our own athletes and explorers. We have entrusted this kit to specialist retailers, who can help you with the selecting the most appropriate gear for the conditions and provide you with essential knowledge and advice for the preparation of your own expedition.

Only available through selected specialist expedition retailers.


The Expedition Windsuit is designed as a windproof layer to be used in conjunction with insulation. Perfect for the world’s coldest climates the suit is compatible with our insulated Expedition suits, jackets and salopettes, and provides expert weather protection at high altitudes or in polar environments. Built with Pertex® Quantum tightly woven fabric the suit is extremely windproof whilst remaining breathable, lightweight and packable. A DWR finish easily sheds water although this suit is designed for cold environments where it is likely to be very dry.

It features an adjustable hood with a stiff peak and has been optimised for articulation at the knees to allow for full range of movement on challenging terrain. It has two chest and two Napolean outer pockets, and a two-way extended front zip (ideal for relief). Full length side zips with multiple pullers enable you to put it on and take it off with ease.

Pertex® Quantum Fabric

Pertex® Quantum uses a tightly woven structure to provide a light and soft fabric that allows insulation to fully loft. With down proof construction, a DWR finish and soft feel, it's a lightweight and packable windproof fabric offering excellent weather protection.
