Awesome windbreaker

Perfect fit for running. Trim but not tight. Disappears when not needed. Super soft next to the skin. Love the back vents.

My favorite brand for everything!!

Janji is my favorite gear for life hands down. My latest addition is the Zephyrunner Wind Shell which is super comfortable and functions perfectly. I also also love the Transit Tech Pants, Helio t-shirt, Rover Merino Hoodie, and Thermalrunner jacket. All incredible pieces beautifully crafted.
