OMM Mountain Core Jacket

The OMM Mountain Core Jacket is a highly versatile insulating layer designed for fast-paced mountain activities in variable conditions. Constructed with a lightweight, stretch Flexile nylon shell, it offers excellent wind and water resistance while maintaining impressive breathability. Inside, the revolutionary PrimaLoft Active 125g/m2 insulation provides exceptional warmth with less than half the weight of traditional fleece, ensuring comfort during both high-output efforts and cold-weather rest stops. Built from 64% post-consumer recycled fibres, the insulation performs superbly when wet, making it a reliable companion for wet and unpredictable climates. The soft-lined hood adds welcome protection and warmth when the wind picks up on exposed ridgelines.

Designed for both comfort and performance, the Mountain Core Jacket combines thoughtful features with technical innovation. The open-knit PrimaLoft Active structure traps warm air efficiently while allowing moisture and excess heat to escape, keeping you dry and comfortable through changing intensities. The stretchy Flexile shell provides freedom of movement for running, hiking, or ski touring, while the minimal bulk and packable design make it ideal as part of a layering system under a waterproof shell. Soft cuffs, zippered hand pockets, and a snug fit complete this cozy, functional jacket that’s as ready for alpine adventures as it is for chilly post-run recoveries.
