The Full Description

The Montane Prism Jacket is an insulating yet lightweight jacket that really excels in its field, providing both comfort and conveniance. Filled with Primaloft 40g Silver Eco, the Prism is both water resistant and environmentally friendly, with the fill being made from 70% recycled material. The Prism is a winner of 'Best Value' in Trail magazine and earned a recommendation from Singletrack magazine.

While you're patting yourself on the pack for helping the environment, you'll be equipped to tackle the outdoors with this jacket. Designed as a mid layer under a shell or a sole jacket in drier weather, the Prism is a great choice for British adventurers and sees use across the UK by multiple mountain rescue teams. The filling is fast drying and very packable, something that comes into its own with the quirky pocket feature (the jacket can be stowed into its own pocket, creating a little pillow you can use for camping.) The Prism is made from Per-tex Microlight ripstop material, which is windproof, water repellent and fast-drying, a must in our unstable climate.

The hood is fully adjustable and is easy to roll up inside the collar when you don't need it. It even comes with a beardguard near the chin for added comfort for all you grizzled veterans. The Montane Prism Jacket is an extremely warm jacket that provides lots of insulation but isn't bulky like some insulators are. Instead, the Prism weighs just 418 grams and packs away into a tiny pillow. It's a great choice for anyone who wants a winter jacket under a shell or a solo jacket for less intense weather. Little extras like hand warming pockets, fully baffled YKK zippers and reflective panels help make this a versatile purchase that you'll wear again and again.

Caring for your Montane Jacket

  • The Prism Jacket uses PERTEX® fabric which contains a Durable Water Repellency (DWR) as the first barrier in keeping you dry. Clean your garment in order to maintain this.
  • Machine wash in warm water at 30°C/86°F with a mild detergent. MONTANE® recommends that you use Nikwax Tech Wash.
  • Do not use fabric softeners or bleach.
  • Drip dry.
  • Your jacket may need occasional re-proofing to restore the DWR. MONTANE® recommends Nikwax TX Direct.

Montane Prism Synthetic Insulated Jacket

Montane Prism Synthetic Insulated Jacket Top jacket for mountain/hiking in changeable conditions light warm and pack-able, looks cool.

Warm and versitile

Great jacket for warmth / weight ratio. My only gripe is the fit. Inside lining on the arms is cut too long and often sticks out the cuffs when putting the jacket on. Cut is quite large on the chest so can also seem a bit baggy for me. Otherwise a good jacket and excellent value for money.

is it a pillow, is it a jacket, no its super prism!

great little piece for winter walkers. not waterproof but really resistant and kept me warm even when it got wet on a really windy, rainy day. windproof and folds away into a pocket for camping. Had a bit of a stiff night sleeping on a groundsheet but this thing works as a comfy little pillow. The insulated hand warming pockets are a nice touch. Much prefer this to my down jacket for day walks in cold weather
