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.

New Favorite

This jacket has replaced my Patagonia Houdini. It is as light, softer, has an adjustable hood, and best of all zippered hand pockets in addition to the chest pocket. Looks good enough that I wear it around town, not just for running. My only suggestion would be to add a loop inside the chat pocket so you could attach a mini carabiner when it is stuffed in its pocket. I’m between and medium and large for jackets. The medium Janji Rainrunner fits me better, but the large Zephyrunner is perfect for me.
