OMM - Men's Core 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, the heavier version of the 75g/m2 PrimaLoft® Active fabric used in the Core Vest and Core Hoodie.

PrimaLoft® ACTIVE Insulating Fabric weaves PrimaLoft® fibres onto a mesh, giving a super high volume and open structure. Fabrics insulate by trapping pockets of air that the wearer’s heat cannot pass through. Core structure is exceptional at creating these pockets. However, the openness also allows for a light breeze to disturb these air pockets and remove the insulation effect. Core uses this to its advantage; put a light shell on over the top for the best possible warmth to weight layer and then when you get too hot adjust/remove only the shell and you can keep pushing hard to the summit without a bulky layer to stash.
