Montane Womens Phoenix Lite Jacket Stratus Grey Information

Season : Sale

Brand : Montane


What is the Phoenix Lite?

The Phoenix Lite is a lightly insulated, packable and highly versatile jacket featuring a PrimaLoft Silver Thermoplume insulation and Pertex outer fabric. It excels at providing high amounts of warmth without the excessive bulk and weight. 

What is it made of?

Insulation: The beating heart of this jacket really is its impressive insulation. Montane feature 115g of PrimaLoft Silver ThermoPlume insulation with Cross Core technology in the main body. Don't be ashamed if you haven't heard of it before, we hadn't either! This brand new form of insulation from PrimaLoft is a jump forward in terms of synthetic insulation; it essentially copies the shape of down but using synthetic fabrics, meaning it retains the same compressibility, feel and loft as down but with the added benefit of performing in damp conditions. 

Now, onto the 'Cross Core' part (get ready for some nerdiness). Cross Core, in simple terms, mixes the already proven and incredibly high performing PrimaLoft synthetic insulation with Aerogel. Originally developed and used by NASA in their aeronautical applications, Aerogel is made from 95% air and is the lightest solid material known to man. This incredible material boosts the warmth of the jacket substantially without adding more than a few grams of weight. All of this insulation is kept in place via a micro-baffle construction, minimising the weight and pack size whilst keeping warmth high. 

Outer fabric: Surrounding this clever insulation is a tough, reliable 20D Pertex Quantum nylon fabric. A durable water repellent coating provides valuable weather protection if you happen to get caught out. Please note, it is not waterproof, always take a shell... because, knowing our less than predictible weather conditions, it will rain!

What are the features?

Starting at the top, an insulated hood keeps your head nice and toasty and can be worn under a helmet thanks to its snug fit - ideal when climbing or belaying. Two zipped hand pockets store all the essential items that you want close to hand, while an elasticated hem and cuffs seal in the warmth. The YKK Vislon front zip has an internal storm flap behind it helping to eradicate the cold spot caused by zips. 

How does it fit?

The Phoenix Lite features a slim, tapered fit with an average length (68.5cm back length). It's primarily going to be used over just a baselayer/t-shirt, so it'll work best when sized snug. Articulated arms prevent the hem of the jacket lifting excessively when reaching above your head. 

Where does it fit in the layering system?

The Phoenix Lite is designed to offer plenty of warmth when worn as either a midlayer or outer layer. If the conditions warrant it, you'll be able to fit a shell over the top without a problem, however it really shines when worn on its own just over a baselayer.

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.
