The Core range look is as unique as its performance. The adaptable layer is suited to activities requiring different levels of exertion. As an outer layer the mesh fabric releases excessive heat and moisture whilst adding an overlayer traps in heat when its needed. The Core Fleece Jacket uses the 125g PRIMALOFT ACTIVE Insulating Fabric Technology the thicker version of the 75g PRIMALOFT ACTIVE fabric used in the Core Vest 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 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.
