Designed to provide protection from the elements, On Running's WEATHER is a windproof running jacket for men that's ultra-efficient for running because it's lightweight and breathable.

Made from ultra-lightweight Japanese fabric, this model offers complete ventilation and fast drying, while its ultra-stretch polyester and ethane fabric features a micro-ventilation pattern for total breathability and ease of movement.

In addition to its reflective details for visibility in the dark, this jacket conceals vents and folds into its own pocket to take it anywhere.
