OMM Core Vest｜Ultralight Active Insulation, just 72g, that changes temperature regulation

So light you forget you're wearing it, yet surprisingly warm.

Cold morning rides or winter hikes. It's cold when you start moving, but then you get hot after a while. The OMM "Core Vest" addresses this unique dilemma of outdoor activities.

It uses the innovative insulation material "PRIMALOFT® ACTIVE." By directly weaving padding with an animal hair-like structure into a mesh, it achieves both excellent warmth and breathability.

Worn alone, it quickly releases excess heat and moisture, and layered under a shell, it provides high insulation by utilizing an air layer. It's an insulation that truly allows you to "stay active while wearing it," flexibly adapting to environments with large temperature swings and changes in activity levels.

The Core Vest uses 75g/㎡ PRIMALOFT® ACTIVE. At an astonishingly light 72g, it won't be a burden in your backpack or bikepacking gear.
