A modern mountain essential, the Montane Prism Vest delivers the same trusted balance of warmth, weight, and packability as the iconic Prism Hoodie, in a streamlined, hoodless design. Filled with PrimaLoft® insulation, the vest offers excellent thermal efficiency and maintains warmth even in damp conditions. The PERTEX® Quantum outer fabric is lightweight, windproof, and durable, with a water repellent finish that helps shed light rain and snow while protecting the insulation’s loft. Self sealing armholes and an adjustable hem help lock in heat without adding bulk. Practical storage includes pack compatible hand pockets and a secure internal chest pocket for essentials.
