This winter sees the launch of our new FIRESTORM™ family of down insulation, including the Kryos, Xeros, and Exo jackets, and our new Kryos pants.

Developed as part of an extensive 3-year R&D project with some of the world's leading alpinists; FIRESTORM™ is the lightest, most efficient, most protective down-filled insulation we have ever developed, for Alpinists needing the very lightest warmth in real-world conditions.

The Xeros Jacket and Xeros Women's Jacket are the younger siblings of the Kryos Jacket used by Tom Livingstone on the first ascent of The Great Game on Koyo Zom last year. The protectiveness of the FIRESTORM™ construction and outstanding hood design remain, but the jacket's weight has been reduced, making this a perfect jacket for everything from lightweight expedition use to ski touring or alpine climbing. Lab testing has shown that the Xeros is a full 20% warmer than an equivalent stitch-through baffle jacket. The weather resistance of this garment also means that environments traditionally reserved for synthetic jackets are now opened up to a down jacket, with the associated warmth, weight and bulk benefits this brings.
