Ultralight Air-Permeable Primaloft Insulation

An new concept in active insulation, the OMM Core Range is made entirely from PRIMALOFT® ACTIVE ultra-light insulating fabric. Built from a synthetic plume woven through a knitted mesh, Core offers the warmth of a fleece butless-than half the weight. Paired with a shell, the Core is an incredibly effective insulator; but, thanks to near-total air permeability, the lightest breeze can take away that heat. This allows you to keep your Core layer on even when you have warmed up and you can thermoregulate by removing/unzipping your low bulk shell (eg.Sonic windproof at 49g). A true valley to summit piece. Core works wet or dry with incredible wicking properties to ensure you won’t stay wet for long.

The Core Fleece Jacket uses the 125g PRIMALOFT® ACTIVE Insulating Fabric Technology.

Go even lighter and try 75g PRIMALOFT® ACTIVE fabric used in the Core Vest & Hoodie.
