When the temps plummet and the altitude climbs, we reach for the Positron Pro Hoodie. Rab built this expedition-grade puffy for serious cold-weather performance, using 800-fill-power goose down and full boxwall baffle construction to eliminate cold spots and maximize warmth during exposed belays, summit pushes, and nights above the snowline. The tough Pertex® Quantum Pro shell sheds wind, snow, and abrasion, while the helmet-compatible hood, dual insulated chest pockets, and articulated sleeves provide all the technical features we need for vertical travel. Inside, mesh stash pockets and a zip security pocket keep gear close at hand, and the dual hem adjustment seals in heat. Built for high-alpine reliability, the Positron Pro is the kind of insulation we trust when the margin for error is razor-thin.
