Product Insights
The On Core Running Jacket is a 159g windproof knit shell that packs into its own pocket to grapefruit size mid-run, trading heavy downpour protection for breathable wind-blocking, adjustable ventilation, and a stretchy athletic fit that moves freely over layers. Its recycled polyamide fabric resists wet-out from light rain and avoids membrane delamination, while reflective trim and a secure hem drawcord make it a purposeful cold-weather layer that sheds heat when needed.
