Lightweight warmth for the cooler seasons, without the bulk.

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.

  • Articulated arms with engineered tailoring
  • Slightly larger chest and bicep dimensions allow for winter layering
  • Fully adjustable roll-away insulated climbing helmet compatible hood with stiffened peak
  • Full-length two-way YKK® VISLON front zip with internal storm flap
  • Two deep A-line handwarmer pockets with fine microfleece lining
  • Two zipped chest pockets
  • Internal left hand mesh pocket for glove and water bottle storage
  • Stuffs into right hand pocket with internal carabiner loop for when not in use
  • YKK AQUAGUARD® VISLON® zips for use in icy conditions
  • Easy grab ergonomic grippy pulls for use with gloves or mitts
  • Shaped cuffs and adjustable hook and loop tabs
  • Adjustable hem with two-sided cinchable drawcord
