The alpinist's cold-weather refuge.

Few pieces of mountain kit carry the kind of track record that the Rab Neutrino Pro Hoody has built across decades of serious alpine use. This is the jacket trusted by alpinists on winter ascents at altitude, on expedition approaches in extreme cold, and on the kind of days when the margin between comfortable and dangerously underdressed is measured in insulation quality rather than decisions made on the ground. Built with 800FP down treated with Grangers Down Defend inside a snow-shedding Pertex Quantum Pro outer, the Neutrino Pro Hoody offers reliable warmth, exceptional packability, and a feature set designed specifically for vertical use in serious winter conditions. The fully adjustable, helmet-compatible down-filled hood with a stiffened peak provides genuine high-altitude head protection and fits over a climbing helmet without restriction. A 2-way YKK VISLON front zip with insulated storm flap allows precise temperature control in either direction, and cuff adjustment with elastication creates a glove-compatible seal at the wrist during cold belays and high-camp nights. An internal zipped chest pocket, two zipped hand pockets, and an internal mesh dump pocket cover every storage requirement on route. When the winter route calls for real warmth and real performance, this is the jacket that answers.
