Light-weight windbreaker shells are perfect for runs, and Saucony’s Ethereal Jacket for women takes that base and adds a reflective material as well as an LED light on the right sleeve that effectively wakes up those darn drivers texting and adjusting the radio instead of watching the road. It’s water and wind resistant and the LED holds a charge for about 2 hours. Now, if only we could muster a marathon in that time.
