I am Janji fan as most of my running gear is Janji (running shorts, t shirts, tights). I bought this jacket for winter runs (Bay Area). Initially I really loved the jacket as I could run with only a t-shirt and this jacket in low 40s temp without any issue. However over few days the pilling started inside the jacket (specially at chest level where the jacket touches the t-shirt). And then in Jan as it got colder I started zipping up to the top and within a week the top inside part of the jacket started fraying. Not very happy about this purchase as I spent $150+ on a jacket and the quality is not there.
I got the xl jacket when I normally wear a large size shirt. I am about 6ft 1 in with a pretty broad chest. I am glad I sized up because it fits perfectly. The jacket is extremely comfortable and easy to wear. It can keep you pretty warm on a breezy 60 degree day. There is a portion in the back that is not insulated which allows body heat to escape and cold air to get in. I have worn in pretty moderately and there is some fraying around the collar. Small wisps of cloth starting to emerge which has me concerned for the longevity of the jacket. Bought it on sale however and not disappointed.
Excellent, very lightweight running jacket. Weighs next to nothing but seems well constructed. Useful pockets are a boon, and apparently it wraps in on itself although I haven't had a chance to try it.
I've been really pleasantly surprised with this jacket. It is super lightweight, but able to run plenty warm in 20 degrees fahrenheit with just a long tech tshirt underneath
This instantly became my favorite jacket for running or under a shell when cold weather hiking. On its own it is warm but so light, comfortable and well made. It fits and feels just as great as the Arcteryx Atomic jacket, but less expensive. Appreciate the 3 zippered pockets. I alternate between medium and small jacket size, and returned the medium for a small as it fit much better.
I love the look of this coat and how it fits and feels. However I question in what way is it insulated. My wind breakers are warmer than this. And wind cuts right threw it
