A superb, insulated jacket for cold and damp conditions.

The Montane Flux Jacket places its emphasis on completely on insulation and comfort, designed for tough mountain use and alpine climbing.

It's filled with 100g PrimaLoft® SILVER ECO synthetic insulation around the body, with 60g around the arms and hood, and an extra 60g positioned in front of the hand pockets for extra warmth.

You have a fully adjustable helmet compatible hood with three points of adjustment and wired peak,  and the whole jacket packs neatly into its own pocket ready to stash in your pack or clip to your harness.

Overall it's an essential mountaineering jacket, tested against some of the most changeable weather conditions on Earth.
