OMM Mens Core Zipped Vest

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 (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.

With a full-length zip and warm draft excluder collar, this is a great mid-layer equally at home on the fells as it is on a rest day mooch. The Vest fit allows for good insulation without extra bulk or overheating.

The Core Zipped Vest uses the midweight 125g/m2 PrimaLoft® ACTIVE Insulating Fabric Technology.
