Arc'teryx's lightest, most packable synthetically insulated hoody keeps you comfortable on cold winter runs. Its Fortius Air 20 face fabric balances airflow with wind resistance, and a PFAS-free DWR treatment repels water. Mapped 25gsm Coreloft at the front, sides, and sleeves insulates. A streamlined hood adds protection, run-specific articulation frees you to move, a zippered pocket provides bounce-free storage, and tuck-away flip-mitts in the sleeves keep your hands warm.
