The Neutrino Pro jacket has been a mountaineer favorite for the past twenty years. Updated with a new arm baffle design and 100% recycled fabric, the new Neutrino Pro now has increased mobility and a lighter footprint. Perfect for climbing in winter conditions, this alpine puffer is filled with 800FP goose down.

This ultra-high loft down is extremely insulating, even in sub-zero temperatures. The Neutrino Pro utilizes a wind and weather resistant 100% recycled Pertex® Quantum Pro outer, offering shelter from blizzards, snow, and drift. New anatomically engineered twisted arm baffles enhance the pre-curvature of the arm, allowing for complete freedom of movement. Designed specifically with the demands of winter climbing in mind, whether you're ascending a frozen waterfall or belaying from an exposed ledge, the Neutrino Pro offers unhindered movement for competent 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 heavy-duty two-way YKK® VISLON® front zipper for easy use with a harness. Designed for durability on rough terrain, the shoulders and upper sleeves have been reinforced with Ripstop reinforcements. A true staple for alpinists, the new Neutrino Pro is ultra-warm, durable, and perfected for vertical adventures.
