Lightweight mountain insulation that's versatile enough for year-round wear.

Comfortable and effective whether worn as an outer jacket or mid-layer
Synthetic insulation provides effective warmth even when wet
Windproof, water resistant, fast drying outer fabric
Easily packable - stuffs into its own pocket

Their most versatile insulation piece, the Montane Prism Jacket is an essential piece of mountain clothing whether you're actually headed to the mountains or not.

Made using 40g PrimaLoft® SILVER ECO insulation throughout, inside a windproof, water-repelling PERTEX® Microlight Mini Rip-stop outer shlel, it's warm and weatherproof yet lightweight enough to be worn on the move.

Used and abused by Mountain Rescue teams across the UK, the Prism makes a very warm midlayer within any shell system, and is very effective if worn alone as an outer jacket in drier weather.

PERTEX® Microlight Mini Rip-stop outer fabric - windproof, fast drying with exceptional durable water repellency
40g PrimaLoft® SILVER ECO insulation throughout - warm, packable and exceptionally fast drying (handwarmer pockets are insulated at both sides for double the effect)
PEAQ Synthetic lining - supremely comfortable next to the skin, highly breathable and fast drying

Two hand warmer pockets with YKK reverse coil zips, not in way of backpack hip belt or climbing harness
Internal zipped chest pocket on left hand side, ideal for storing GPS or mobile phone
Jacket can stuff into right hand pocket with internal carabiner loop

  • Full length, reversed and baffled YKK front zip with internal press-stud storm guard
  • Roll over chinguard lined with brushed fine microfleece
  • Low-bulk stretch bound cuffs - can be pulled up forearms to aid cooling
  • Three point adjustable hood, helmet compatible, with wired peak, can be rolled away and securely stashed
  • Adjustable hem prevents spindrift entry while trapping warmth inside
  • Reflective details
  • Rear external Montane hanging loop
