It’s no secret we love options, and the versatile Convertible Running Jacket by Nike (created with 100% recycled polyester) is built for varying weather conditions. Take the jacket out for a run on a overcast day and don’t worry when the sun pops out. Nike has designed this jacket so you can remove the sleeves, which easily fit in their own pocket stitched on back of the jacket. One of our favorite touches is the MP3 friendly design, the interior is outfitted with a media player pocket and a simple cord management solution.
