It's great so far. Wish it had another key pocket lower down near the bottom. Love the snap to go unzipped

Love it

Great for cool day runs. Love the comfort, not overly hot when you work up a sweat. Used on a few 40-50 degree days, was perfect with a long sleeve under.

Very light weight.

Bought this for running on cooler mornings and does the job well. It's extremely light, but surprisingly warm considering. It's a bit tight around the forearms, and rides up a bit at the base, so I bought another a size up and it's a bit more comfortable. Wearable in either size though.

Rolls up so light can put it in my shorts pocket and keep running and forget its there most of the time. Or tie it around my waist. So far quite pleased with it. Will see how it holds up as we get deeper into winter.

Great for Running!

Lightweight and fits perfectly

My favorite running jacket

I actually have 2 of these jackets: midnight and spray dye. I got the second one because I loved the first one so much. These are super lightweight and the build quality is excellent. I would recommend ordering a size up as they run a tad small as it’s more of a slim fit. Regardless, this is hands down my favorite running jacket for those brisk early morning runs or late night sunset strolls.

Chill jacket

It's a really thin jacket, if you overheat easily I'd say get this. It's also pretty resistant to wind and dries really quick. I'd say it's a chill jacket to wear as well if you're into that

Great for Slightly chilly morning runs

Good feel and quality. It’s easy to pack up into a little pouch. I love the top button. Makes sense while running when u need more airflow but don’t want the jacket sliding off your shoulder

Must have rain running gear

Great for spring and fall rainy run days, weights nothing.

Great cold weather jacket

I over heat on runs, so my typical approach to 20-35 degree weather is Janji pants, a random race premium long sleeve shirt, and a light weight reflective vest. This is great unless it rains. This jacket solves that scenario for me perfectly, as I can unzip and use the internal snap so it doesn’t flap around and drive me crazy when it isn’t actively raining, and then zip back up again when the rain starts. 30-40 degree and rainy days go from miserable and risking hypothermia to no problem

Great jacket but…

I wish the pocket were a shade bigger for my phone. Maybe a hooded option too. If neither of these bother you, then this coat is perfect and get it
