The temperature is dropping, but your motivation isn't going with it. Not with this adidas by Stella McCartney running gilet. When all you need is just a little more warmth and protection, go ahead and zip this layer on. It fits loosely, which means it's ideal for layering. Plus it's water-repellent and has an attachable hood and adjustable waist, so while the style and weather can change, your plans don't have to. Reflective details catch the light. Made with 100% recycled materials, this product represents just one of our solutions to help end plastic waste.
