Introducing the groundbreaking OMM Core Range, crafted exclusively from PrimaLoft® ACTIVE ultra-light insulating fabric. Constructed with a synthetic plume intricately woven through a knitted mesh, Core provides fleece-like warmth at less than half the weight. When paired with a shell, the Core serves as an exceptionally efficient insulator. Its near-total air permeability, however, ensures that even the gentlest breeze can dissipate excess heat. This unique feature enables you to keep your Core layer on, allowing thermoregulation by removing or unzipping your shell (e.g., Sonic windproof at 49g). A true valley-to-summit piece, Core excels in both wet and dry conditions, boasting remarkable wicking properties for rapid drying.

The Core Zipped Vest, featuring a full-length zipper and warm draft excluder collar, stands out as an excellent mid-layer suitable for the fells or a leisurely rest day. The Vest fit ensures effective insulation without unnecessary bulk or overheating. Utilizing the midweight 125g/m2 PrimaLoft® ACTIVE Insulating Fabric Technology, it represents a heavier alternative to the 75g/m2 PrimaLoft® Active fabric found in the Core Vest and Core Hoodie.

ADAPTABLE INSULATION

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.

HALF THE WEIGHT & PACK SIZE

A single mesh fabric holds the insulation plume in place, reducing the need for extra fabric layers and halving the weight and pack size.

FINEST QUALITY SYNTHETIC INSULATION

At OMM we always choose synthetic insulation over down to be sure that we can get warm even when everything is wet. We believe PrimaLoft® make the best synthetic insulation and so it is an easy choice for us. 125g/m2 PrimaLoft® ACTIVE uses 64% post-consumer recycled material, it is also bluesign and Oeke-Tex approved.
