Storms roll in without warning, but the Firewall Jacket ensures we stay protected through every summit push and ridgeline traverse. Designed for rugged mountain environments, this shell features 3-layer Pertex® Shield fabric for unbeatable waterproofing while maintaining breathability on strenuous ascents. When the wind howls and rain lashes down, the adjustable hood with a stiffened peak shields our face, while underarm vents let us regulate airflow without sacrificing protection. Built with reinforced durability to handle abrasion from rocks and heavy packs, the Firewall is ready to take on the toughest conditions, season after season.
