Chance GRID Pertex® Shield Air™ Storm Jacket

Positively impacting the world through running. Chance are passionate about building the finest running apparel on the planet and using it to build a community of environmentally and socially conscious runners, empowering them to make a positive impact on the world in which we run.

Created in collaboration with Pertex® through a year of prototyping and real-world testing. The Chance Running GRID Storm Jacket uses the first PFAS-free Pertex Shield Air™ fabric—a 3-layer, ultra-light, air-permeable fabric offering elite waterproofing and breathability. Race-proven and mountain-ready, it’s built for those who run through the storm, not around it. The Chance GRID (Gear Research & Innovation Division) spent a year designing, prototyping, and validating their first fully waterproof jacket. Supremely lightweight, the jacket packs into your palm and the gusseted back prevents pull or distortion when worn with a pack.
