What is the Prism Jacket?

The legendary Prism jacket has been around for a while now and has firmly cemented itself within just about every outdoor enthusiast's kit cupboard. It's difficult to pinpoint why, but it's one of those jackets which you'll reach for time and time again, no matter what the weather is doing. This latest incarnation includes a design update, a far better fit and a host of other technical refinements. 

What is it made of?

Insulation: Inside the Prism you'll find 40g of the incredibly popular PrimaLoft Silver. PrimaLoft is a fully synthetic insulation which is virtually unaffected by moisture, making it one of the most versatile forms of insulation for one of the most versatile jackets. 

Outer fabric: Surrounding the insulation is a 100% recycled Pertex Quantum fabric. This fabric provides a tough yet breathable barrier and features a durable water repellent coating to resist light showers and snow. Having used the jacket for a week in the Lake District, we can confirm that it does put up a good fight against sudden downpours. To top it off, this fabric is completely windproof. 

What are the features?

The main attraction to the Prism is that it just gets on with the job; it has everything you need and nothing you don't. You get two nicely sized hand pockets, a chest pocket, elasticated cuffs, a drawcord on the hem to seal in warmth and a helmet-compatible hood with rear adjustment. The entire jacket packs down into one of the hand pockets for easy transportation. 

How does it fit?

The Prism sits in Montane's 'active mountain' fit block, meaning it sits snug for fast-paced mountain activities. To put this into perspective, Montane's fit model is 6ft 1", has a 39" chest and wears a medium. The length is spot on and it does have enough room for additional layers if particularly cold. 

Where does it fit in the layering system?

The Prism can either be used as a lightweight yet warm outer layer, or as a super warm midlayer in particularly cold/wet conditions. It also makes a great over-layering piece if you need a little more warmth when stopping for lunch or to map read.

Care & Advice

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.

"I first noticed Trekitt by their fantastic YouTube videos, which were very informative and honest. So I headed on over to the website and looked at various coats to try and determine which to go for. Being a bit of a muppet I didn't really have a clue what was best so contacted customer services who directed me to a few coats but said he would go away (over the weekend!) and think some more and get back to me Monday. I thought it was just a fob off as the conversation had been going a while but low and behold on Monday morning an email appears with suggestions! I was so pleasantly surprised that if I hadn't already been convinced to buy with them, it was concreted then. I bought 2 coats from them the same day and very shortly after they appeared. The fit was exactly as they had suggested it would be, the quality of the items was as described and I am very happy with them. In this day and age of large companies taking a backward step from customer service, it is such a breath of fresh air to be treated with such a personal touch. If I ever need anything outdoorsy, I know exactly where I'm going."
