    • Montane Flux Jacket Review

      By Peter on 5
      A bit of a story here. This is my third Flux jacket. My first one which is green, was nicked by my wife! My second one which was black, was nicked by my daughter and so I have had to purchase another black one. Terrific jacket! You can practically live in it. No need for fleeces. They have had their day. This is the now and this is the future! Exceedingly warm and great for just about anything whether stationary or moving.
      YES Peter would recommend this item

      By Howard on 5
      Bought the Flux to replace my Prism 2 thats now keeping my son warm! Excellent jacket - a little warmer than the Prism, better pockets and the slightly longer style is more comfy. Would definitely buy one again - especially at this price. Wear it almost every day - brilliant!
      YES Howard would recommend this item

      By John on 5
      Cant fault this jacket, its windproof qualities are fantastic, tested in the lakes during this recent spell of high cold winds. Comfy and the features and pockets are excellent. Weight to warmth is fantastic, a top purchase :-)

      By Mick H on 5
      This jacket was one of the best investments Ive ever made kitwise. Its simply indispensable when the temperature gauge really starts to drop. Love it to bits and its far easier to look after than a down jacket.
