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.
