For the coldest of days, reinforcements were called in. Drawing inspiration from the development of the VLVInsulator, this arctic-ready cap features a breathable recycled outer shell treated with C0 DWR for reliable performance and protection. Integrated airBEAM™ venting, lined with COOLmatic | EXP™ fabric infused with carbon, enhances temperature regulation from start to finish. To keep the cold at bay, the design harnesses the natural power of Sorino | WS light loft insulation—a refined blend of wool and silk that delivers exceptional warmth and thermoregulation with minimal bulk. Insulated earflaps and neck protection can be folded up or down to adapt to whatever conditions the north wind brings. A true insulator for the head—built for when hell freezes over.
