I've been using the ReGreen windshell as my go-to trail running jacket for months. It compacts down to the size of my fist and stuffs easily into my running vest. It's been a savior in warding off the chills on morning and evening runs. The overall cut is great for athletes with a comfortable hood. The jacket fits over my run vest so I don't have to take the vest on and off during long runs. I also love that it's made from recycled plastic, which is a nice, feel-good bonus on top of a highly functional piece of gear. While the piece is not waterproof, it works well running in drizzle or fog, which is the typical out in the Pacific Northwest.
