The Neutrino Pro Jacket has been a favourite of mountaineers for the last twenty years. Updated with 100% recycled fabric and a new arm baffle design, the new Neutrino Pro now has greater mobility and a lighter footprint.

Perfect for climbing in winter conditions, this alpine down jacket is filled with 800FP 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. Designed specifically with the demands of winter climbing in mind, whether youre questing up frozen waterfall or belaying from an exposed ledge, the Neutrino Pro offers unhindered movement for proficient climbing. Incredibly lightweight and packable for such a warm jacket, the Neutrino Pro can be compressed 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.
