Montane's Flux Jacket is a lightweight piece of winter insulation. Good, useful features make it a popular choice for those who are active outdoors.

Montane says:

Montane sponsor some of the worlds toughest races; in doing so they gain invaluable insight into gear design and performance; its why their gear works;


Designed for moving fast in cold conditions in the mountains. Featuring layered 100g and 60g PRIMALOFT combined in such way as to maximise insulation without compromising comfort the Flux was conceived to be more than a simple belay jacket.  

Super packable and encased in PERTEX Microlight that is both windproof and exceptionally fast drying. Tested on the bigwalls of Patagonia`s Fitzroy in some of the most changeable weather conditions on earth.  

| Pertex Microlight Lightweight outer Fabric - A good balance between weather & abrasion resistance against the weight of the fabric. Click Logo to read more...
                       | Primaloft Eco - PrimaLoft ECO insulation uses post-consumer recycled material to create a high loft, thermally efficient, earth-friendly insulation. Click Logo to read more...

The Montane Flux jacket is the ideal winter weight Primaloft jacket updated with pockets where you need them and a well designed hood.

Wear synthetic insulation when you are on the move.  

Although light coloured the Kiwi Flux jacket is more subtle than the photo suggests!
