The Men's Flux Jacket combines a clever construction with a wide array of useful mountaineering features.

Made from 100% recycled PERTEX® QUANTUM ECO fabric, with Primaloft® SILVER ECO insulation and PEAQ Synthetic ECO lining, the jacket is fully showerproof, completely windproof, fast drying, comfortable and locks in warmth excellently. The result is a jacket of the utmost reliability, with every consideration made to comfort and practicality.

The features are superb. The helmet-compatible hood is wire-peaked and fully adjustable, with added insulation for when you're out on longer or colder days. 

Two deep A-line handwarmer pockets ensure that your hands are kept warm when they're not gripping the rocks or poles, and then there's an internal mesh pocket for gloves and water bottles, with two further chest pockets.

The YKK VISLON® and AQUAGUARD zips are waterproof (the former including a stormflap) and resistant to ice, and there are ergonomic pulls for use with gloves and mitts.

With numerous adjustable features to personalise the fit and keep out the elements, and articulated arms for fluid, light motion, the Flux is an excellent example of a mountaineering jacket.

It even folds into its own pocket and has a carabiner loop for when it's not needed.
