BREATHABLE 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.
WARM EVEN WHEN WET
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.
COMFORT & PERFORMANCE
We can quote all the performance figures we like but what really sets the Mountain Core apart is the sheer cosiness of it. You will fly down those final descents, knowing you get to pull this on at the end of your run. But be warned, it can be very hard to take it off once your snuggled into it!
