The Arc'teryx women's Proton AR Hoody is the warmest option in the Proton series, offering all-round hooded versatility to provide wearers with a balance of airflow and insulation. It's designed as both a warm softshell outer and to be worn as a robust mid layer under a waterproof shell. It does this by leveraging advanced material technologies and two weights of Coreloft™insulation, to provide thermal protection, while its shell and liner allow ventilation. This system prevents vapour accumulation and lets the Proton AR regulate your comfort through a range conditions experienced in seasonal outdoor settings.
