The Core Beanie brings OMM's PrimaLoft ACTIVE insulation to a close-fitting headband-style beanie, giving fleece-level warmth at a fraction of the usual weight and pack size. The insulating fibres are woven through a fine polyester mesh rather than wadded in, so the fabric stays air-permeable and keeps performing even when it gets wet, unlike a standard fleece. At just 18g it disappears in a pocket until you need it, and pairs easily with a windproof cap or hood over the top to lock in extra warmth on cold, exposed sections. Minimal seams and a stretch fleece construction keep it comfortable for hours of wear.
