Neutrino Pro Jacket - Men's

What Our Gearhead® Experts Are Saying:

"This jacket is built for real mountain conditions. I’ve worn the Neutrino Pro on cold belays and frigid summits—it’s insanely warm, resists wind and snow, and still fits comfortably over a harness. The hood is a standout—it actually works with a helmet and seals out spindrift."

When the cold hits hard and the wind won’t let up, we count on the Neutrino Pro Jacket to keep us moving and motivated. Rab’s iconic alpine puffer is built for mountaineers, ice climbers, and winter trekkers who demand high-loft warmth and rugged protection in extreme conditions. Wrapped in weather-resistant Pertex® Quantum Pro fabric and filled with lofty 800-fill hydrophobic down, it delivers an unmatched warmth-to-weight ratio in bitter alpine environments.

We appreciate the thoughtful mountain-first features—like the helmet-compatible down hood, belay-ready two-way zipper, and reinforced ripstop shoulders—that make this jacket feel tailored to life above tree line. Pre-articulated sleeves and an adjustable hem enhance mobility when reaching or roping up, and multiple zippered pockets keep essentials in reach without compromising your layering system. Whether we're freezing at the crag or racing daylight in the high peaks, the Neutrino Pro is our shield from the elements.
