The Mountain Core Jacket combines OMM's PrimaLoft Active insulation with a lightweight, wind-resistant Flexile shell to create an insulating layer that stays breathable even when your output varies. PrimaLoft Active is built from a synthetic plume woven through a knitted mesh, delivering the warmth of a fleece at less than half the weight, and it keeps working wet or dry thanks to fast wicking that stops you staying cold and damp for long. Using the 125g/m2 weight means 65% of the insulation comes from recycled sources. The stretch nylon Flexile shell resists wind and water while staying breathable, well suited to mixed mountain conditions, and the cozy lined hood adds welcome protection from cold winds.
