Product information

The Montane Men's Prism is an insulated jacket that’s been a firm favourite since way back in 2008. There have been many iterations as the design team have continued to improve fit and introduce technical refinements. The current version uses weather resistant Pertex Quantum, 100% recycled PrimaLoft Silver insulation and is upgraded with a lightweight nylon lining. The Prism Jacket has a climbing helmet hood and good pocket options, and packs down into its hand pocket so it’s small enough to be kept in a daypack. For a warm, windproof weather resistant layer that’s ready for almost any weather change, think no further than the Prism.
