The Active Jacket is designed to keep you out there, whatever the weather. Specifically woven for protection against brisk winds. So you can skip the extra layers on those chilly winter days, staying snug on the move. Ripstop fabric is known for being super lightweight and durable. Interwoven in a tight crosshatch pattern, it protects against unforgiving wind while feeling almost weightless. Whether you're cross-country running or a city sprawling, you don't have to carry any unnecessary bulk.
