The Neutrino Pro is ideally suited for climbing in winter alpine conditions. Easily deflecting snow and spindrift, it has a weather-resistant Pertex® Quantum Pro outer with ripstop for added durability. It’s filled with 800FP down in stitch-through baffles and compresses down small enough to stash in a pack. Whether you’re questing up a frozen waterfall or belaying from an exposed ledge, the Neutrino Pro lets you move freely with fine-tuned sleeves for complete mobility.
