Godsend for Running in all Weather
As a beginner runner, I was a bit lost at how to dress for running in both Midwest winter temps and more mild DC winter temps. I bought this jacket when it was 50% off and it ended up being my most used item by far of 2025. Super high quality, very water proof, but the venting in the back is essential to prevent you from over heating. Could not recommend this more!
