Maximum warmth and comfort, with minimum weight for mountain use.

The MONTANE® Prism Jacket is extremely light and offers maximum warmth with minimum weight. Made from Pertex Microlight Rip-stop fabric, it's water repellent, windproof and breathable.

Using Primaloft Eco 40g insulation the body will be kept warm from the elements and as it is ultra light it is hassle free to store away in warmer conditions.

The reversed full front zip allows the body to be fully ventilated when it is warm and provides protection when it is cold.

The adjustable draw-cord hem and elasticated cuffs ensure a close fit to the body but give freedom of movement.

2 double insulated chest pockets and insulated hood with non-whip face aperture draw-cords keep the head and hands as protected as the body, and in dark conditions the 3M Scotchlite reflective flashes allow for visibility.

This highly breathable and insulated jacket is ideal for the active man who enjoys cold outdoor activities.

Good jacket, very dodgy zip, 22 March 2017
By ChrisA (Colchester)
Nice light, warm jacket. If layering with micro fleece and base top/t-shirt this will do the job for most UK situations. As mentioned before though the zip is dodgy - sometimes won't zip properly if bottom parts aren't fully connected (easily done) then a real pain to get undone.
If a £20 quid garment can get that right then there's no excuse for a £100 jacket not to.

Good jacket BUT, 24 February 2017
By Mr V Scottish Borders (Scottish Borders. Coldstream)
Great jacket for cool weather in the borders BUT the main zip is a pain at times if you don't insert it correctly before pulling it up and it opens up on you and then you need to forcibly yank to separate the zip to start again. The zip could be a bit larger and better quality to earn five stars

Good jacket dodgy zioa, 25 January 2017
By pgrange (Coventry)
I've had this jacket just over a year and I have to say it's warm, lightweight and more than adequate for my use i.e Sunday morning football, cycling to shops and general wear. What's not so good is the zips. You need to be very careful with the main zip that the two ends are fully inserted before zipping up. A couple of times now I've zipped it up only to find that it's come apart at the bottom. I've been lucky and manged to zip the zipper back down. The pockets on the other hand have been a nightmare! The zip gets snagged in the lining and got stuck. The last time the left one for stuck in lining whilst I was trying to retrieve my passport for security control. I had to force it open and the zip completely gave way and is now broke. The problem is the zips are cheap plastic and low quality. Not what I would expect from Montane. Would I the jacket again? Unfortunately the answer is no. Shame as the jacket itself is nice and warm and comfortable but let down by cheap quality zips!

Not blown away., 11 December 2016
By Ian (Norfolk)
This is an ok jacket. I have found I have to really have to think about layering when wearing it.I have not been impressed by it's thermal quality for its size( compared to much thinner garments I have) and for the cost there are better jackets available. It is not a go to jacket for expeditions for me, more of dog walking in mid autumn. I like its pacability but as I said it doesn't come with me on expeditions so haven't needed to. The hood would fit a helmet well. The pokers fit hands with gloves well and the zippers have great tabs for use with gloves.

As I said an Ok jacket.
