We're working out what we think - we'll add our view here!
A new concept in active insulation, the OMM Core Range is made entirely from PRIMALOFT NEXT 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 NEXT Insulating Fabric Technology, the lighter version of the 125g PRIMALOFT NEXT fabric used in the Core Jacket.
