Ultralight Air-Permeable Primaloft Insulation
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 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 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.
Wear the Core Vest as a super warm first layer in the coldest of events and challenges from the OMM to the Spine and the Yukon Ultra.
The Core Vest uses the 75g PRIMALOFT ACTIVE Insulating Fabric Technology the lighter version of the 125g PRIMALOFT NEXT fabric used in the Core Jacket.

PRIMALOFT ACTIVE Insulating Fabric Technology – 75g
Sizes XS / S / M / L / XL
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 wearers 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 chooses synthetic insulation over down to be sure that we can get warm even when everything is wet. PRIMALOFT make the best synthetic insulation. The NEW PRIMALOFT ACTIVE Insulating Fabric Technology uses 58 post-consumer recycled material it is bluesign and Oeke-Tex approved.
