Men's Rab Neutrino Pro (Deep Ink/Ink) jacket

Since its creation 20 years ago, the Neutrino Pro has remained the favorite jacket of many mountaineers. Revamped with recycled materials and a new arm divider, the new Neutrino Pro offers greater freedom of movement than ever before, and unrivalled eco-friendly features.

This down jacket, filled with RDS-certified goose down and 800 cuin of loft, is ideal for winter mountaineering. Its ultra-light down with exceptional loft is extremely insulating, even in freezing weather. The Neutrino Pro features a recycled Pertex® Quantum Pro outer fabric , which is windproof and resistant to weather conditions such as blizzards, storms and snow flurries. The new twisted upper-limb partitioning is designed to follow the natural angle of the arms, giving you total freedom of movement. Designed specifically for the rigors of winter on icefalls and exposed ledges, the Neutrino Pro lets you move unhindered.

Incredibly light and compressible for such a warm jacket, the Neutrino Pro folds easily into its pouch for stowage in your backpack. It features a fully adjustable, helmet-compatible, down-filled hood with a sturdy two-way YKK® VISLON® front zipper for easy use with a harness. The shoulders and upper sleeves have been reinforced with ripstop for added resistance on rough terrain. Ultra-warm, rugged and designed specifically for vertical ascents, the new Neutrino Pro is THE garment to have for mountaineers.
