A 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 but at less-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 shell (e.g. 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.

With a full length zip, women’s specific fit and handwarmer pockets, this is a great mid-layer equally at home on the fells as it is on a rest day mooch.

The women’s Core Jacket uses the midweight 125g/m2 PrimaLoft® ACTIVE Insulating Fabric Technology, the heavier version of the 75g/m2 PrimaLoft® Active fabric used in the Core Vest and Core Hoodie.

Sizing Advice: We advise going up a size as this is a tight fitting garment.
