Montane Womens Fluxmatic Jacket Saskatoon Berry Information

Season : 2020W R

Brand : Montane

Code : FFXMJ-SAS-

What is the Fluxmatic Jacket?

The Fluxmatic Jacket is one of Montane’s classic designs; it’s been around for years and has remained pretty much unchanged, proving that if it isn’t broken then don’t fix it. It was originally designed as a belay jacket to provide insulation and protection in cold and wet conditions. A belay jacket is designed to be pulled out of your pack when you stop and thrown over the top of your clothing system to provide insulation, like when you’re belaying in cold conditions.

However, the Fluxmatic Jacket is hugely versatile and can be used as a stand-alone jacket or as part of your layering system. Unlike natural down, the synthetic filling in this jacket retains excellent performance even when wet. It’s also windproof, weather-resistant, warm and breathable making it the perfect choice for virtually all UK winter mountaineering activities.

What is the Fluxmatic Jacket made from?

Fabrics: The outer of the Fluxmatic is made from Montane's own Barrier Lite 20D nylon. This fabric is lightweight, tough and features a nice matt finish, meaning it doesn't look too out of place during everyday life. A durable water repellent coating has been added to the outer to increase weather-resistance. The lining of the Flux Jacket is made using Montane’s own Featherlite Mini Ripstop fabric — it’s supremely comfortable next to the skin, highly breathable and fast drying.

Insulation: Ok, let’s get into the stuff that keeps you warm, the insulation. Montane have used the ever-reliable Primaloft synthetic insulation. Primaloft has been around for years and has proven its credentials in some of the worst conditions. Primaloft Silver ECO is made from recycled polyester — in fact, about 28 recycled plastic bottles are used to make one Kilo of insulation, so the insulation in this particular jacket is made from around 6 recycled bottles. Each and every fibre of the Primaloft insulation is coated with a permanent water repellent which means the filling absorbs virtually no water and dries exceptionally quickly. The fibres are also very fine and soft enabling them to be compressed easily yet bounce back to provide the warmth you need.

Montane have used 100g/sqm in the body, 60g/sqm in the arms and another layer of 60g/sqm in front of the hand pockets. This combination provides essential warmth for the body core, freedom of movement for the arms and an extra cosy layer to keep your hands warm when they’re buried in the pockets.

The massive advantage of synthetic insulation over natural down, especially stuff as good as Primaloft, is that it just works better in the wet. This jacket will absorb very little water and will keep you warm even if it’s wet. Despite all this fantastic wet weather performance, the Fluxmatic Jacket is not 100% waterproof! So always carry a shell jacket to keep you fully protected... because it will rain!

What are the main features?

So, starting at the top let’s have a look at the main features of the Fluxmatic Jacket. There’s a fully insulated and well-fitting hood that will fit a climbing helmet underneath. The hood is fully adjustable using an elasticated drawcord loop at the back that effectively reduces the volume and snugs the hood around your head. There’s also a proper wire-reinforced peak to stop the hood flopping down over your eyes and drawcords at the front to pull it all down to seal out the nasty weather; the ends of which are hidden away inside to stop them whipping your face in windy conditions.   

The main zip is an ever-reliable YKK Vislon and is two way to allow easy access to pockets, harness, hip belts etc. In fact, all the external zips are YKK Vislon to ensure consistent performance in icy conditions. The arms have an articulated cut to make movement easier and increase comfort and have been specifically designed to prevent hem lift when you’re reaching up.

Storage is taken care of with four external zipped pockets, two hand pockets and two chest pockets; and there’s a handy dump pocket on the inside to keep water in to stop it freezing or to stash your gloves. The whole jacket can be stuffed into the right-hand pocket which features a carabiner loop to hang it from your harness. The cuffs feature a part elasticated and part Velcro closure to ensure that they seal tightly around your wrists or over gloves etc. and the hem is finished off with dual cord pullers to make cinching it up, even with gloves, a doddle.

How does the Fluxmatic Jacket Fit?

The Fluxmatic fits a little larger than your typical insulated jacket as it's designed to be thrown over all of your other layers. Despite this, there are plenty of adjustment points to get the fit just right if you're not wearing much underneath. 

Where does the Fluxmatic Jacket fit in the layering system?

The Fluxmatic Jacket is a mid-weight, weather-resistant and packable Primaloft synthetic insulated jacket making it the perfect belay jacket. It also works as an insulating layer depending on your activity level and the weather conditions, to be honest, I’d only ever consider this as a mid-layer in extremely cold conditions. It probably works best as a stand-alone jacket for active mountaineering in changeable winter conditions. Layering is not a precise science and there is no one perfect system that will suit every person, situation or the weather conditions. Some of us feel the cold, others, get hot very quickly, but for more advice on using layers please check out this video

How Should Your Insulated Jacket Fit?

Insulated jackets are pedantic little things. Too tight and you'll compress the insulation and limit the warmth capabilities of your brand new jacket, too loose and you'll spend hours warming up the dead space inside the jacket. Getting the correct fit isn't just about aesthetics, it will determine how warm you are. 

The Incorrect Fit

Too loose: A jacket which is too loose will keep you relatively warm, however it will take far longer to do so and will waste large amounts of your precious energy. An insulated jacket works by trapping the natural heat that your body gives off in the fibres of the insulation; this creates a micro-climate inside your jacket, keeping you warm and toasty. If your jacket is too loose, heat will be able to escape through the hem, the sleeves and the neck of the jacket; it's a little like sticking the heating on in your car with the windows cracked open - it will heat up, just incredibly slowly.   

Too tight: A jacket which is too tight is arguably worse than one that is too loose. If your jacket is far too tight, the baffles can compress to a point where the insulation can't loft effectively, limiting the amount of warmth it can trap. Essentially, it won't work! 

The Correct Fit
It's a tricky one to explain, but it's somewhere in the middle. You've first got to consider how many layers you'll tend to wear underneath; will you have just a t-shirt then the jacket, or possibly a baselayer, midlayer and then the jacket? When you've figured out your layers and you've popped your insulated jacket over the top, you shouldn't have any dead space inside. The cuffs and hem should be comfortably sealed around your waist and wrists with room to move. You should be able to lift an arm up above your head without the hem of the jacket lifting more than an inch or so, and the sleeves should be long enough that when carrying out the same motion, they aren't mid-way up your forearm. Your shoulders and chest area should have enough room so that your hands can touch behind your back without feeling restricted. 

Additional Information
Lastly, consider which activites you'll primarily be carrying out while wearing the jacket. Are you primarily using it as a winter climbing piece, or an everyday/dog walking jacket? You'll find that technical climbing jackets tend to feature a shorter cut, while urban and casual jackets feature a longer cut to offer additional warmth with less mobility.
