Maximum warmth and comfort, with minimum weight for mountain use.
The MONTANE® Prism Jacket
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.

Prism jacket rocks., 01 August 2016
By Jeffroq (North Wales)
One of the best bits of kit I own full stop. Very warm and light. Performs well in all conditions. I have used it in freezing weather over a base layer. Also under a shell in the rain. In the winter months I carried it with me across snowdonia and if the temp dropped or I stopped the prism came out and was on. Even in the rain this keeps you warm over your waterproofs so no need to take layers off to get this working. Two of my sons bought them after trying mine out. Stuffs away into the pocket and doubles as a lightweight pillow. Highly recommended. There are probably about 6 weeks if the year in the UK when this wouldn't be worth having in your pack.

Brilliant jacket great weight, great performance can't fault it other than an inside pocket might be useful. Im going to buy a second one whilst i still can!

A great, versatile jacket, that's lightweight yet still has an amazing heating capacity. Great for all situations, especially as it can be worn underneath water proofs. Definitely recommended.

Montane Prism Jacket, 24 April 2016
By I love the Peaks (Manchester)
I have had this Jacket for over 3 years now and can only speak well of this product. I have wore it in any kind of weather you care to mention and it's stood up to everything except very heavy rain which it claims is not waterproof. However it still keeps you toast when soaked. One minor point, be careful around sharp objects, thorns , Barbed wire. The fit is brilliant, the look is great and feels great to wear. This jacket has been extensively tested throughout the Peak District and Snowdonia and would not hesitate in recommending it to anyone wishing to purchase, I would defiantly consider buying another one without hesitation although feel it's going to be some time as it still looks great after three years of constant use. Please Montane don't think about discontinuing.
