Xeros Men's Jacket

The Xeros was developed alongside our groundbreaking Kryos Jacket, part of an extensive R&D project informed by the feedback of leading climbers and Alpinists who were pushing ever harder and higher with lightweight kit. We needed to maximise the real-world protection and warmth provided whilst minimising weight and pack size.

The key lay in the development of our FIRESTORM™ construction, the use of a DRILITE® Loft drop outer shell that radically reduced heat loss whilst offering a much greater level of weather protection that’s vital on committing routes. Underneath this lies a stitch through baffle construction with all its weight and mobility benefits, but without the heat loss normally associated with exposed stitch lines. Each baffle’s fill is optimised to provide the highest levels of loft and thermal efficiency from the 140g of down (size large).

The Super Alpine Hood provides exceptional protection in freezing, windy conditions, with or without a helmet and the 2-way moulded zip is easy to use with gloves. There are two large drop pockets for gloves and other kit you need to keep warm.

Ultra-versatile, the Xeros is a jacket that’s just as useful for pushing your limits on Alpine routes as it is for weekend ski tours in freezing conditions.

Unique DOWN CODEX© code in each product shows where that batch of down has been sourced from, as well as giving precise down content and fill power figures.
