The Neutrino Pro Jacket has been a favourite of mountaineers for the last twenty years. Updated for Winter 2021 with recycled materials and a new arm baffle design, the new Neutrino Pro now has greater mobility and a lighter footprint.

Perfect for climbing Rainier, the North Cascades and 4-5000m peaks worldwide, this alpine down jacket is filled with 800FP, RDS certified goose down. This ultra-high lofting down is extremely insulative, even in freezing temperatures. The Neutrino Pro uses a recycled, wind and weather resistant Pertex® Quantum Pro outer, offering refuge from blizzards, withstanding snow, and spindrift. The new anatomically engineered twisted arm baffles improve arm pre-curve, enabling complete freedom of movement. 

Incredibly lightweight and packable for such a warm jacket, the Neutrino Pro can be compressed into its stuff sack and stored in your pack. It has a fully adjustable, helmet compatible, down filled hood and a tough, two-way YKK® VISLON® front zip for ease of use with a harness. Designed for durability in rugged terrain, the shoulders and upper sleeves have been strengthened with Ripstop reinforcements. A true staple for alpinists, the new Neutrino Pro is ultra-warm, hardwearing, and honed for vertical adventures.
