Nike's new NSRL Transform Jacket is designed for runners who need a versatile jacket that can adapt to a variety of weather conditions. For colder days, the jacket has four removable down pillows to adjust the amount of insulation needed and if it starts to heat up, the pillows can be rolled up and stored in the jacket's chest pocket. It also has a removable hood and sleeves so you can wear it as a vest and the shell is made out of Gore-Tex Infinium for breathability and wind and water resistance.
