Perfect light layer

I’m a petite gal with wider hips (5’1”, 24” waist, 38” hips) and have trouble finding jackets that don’t make me look like a rectangle. This jacket has a great shape that flatters the waist and sits nicely over my bum without feeling tight. It’s breathable and moveable and has almost no weight to it but somehow also feels super warm. The hood is great for extra wind protection and again fits like a glove. I don’t know how janji does it but their gear is truly the best out there!

Perfection is possible!

Very lightweight, very packable. I wore it for the Charleston half marathon when it was mid-30s with a brisk wind. Once I got going, all I needed was one thermal layer and this jacket. I could feel that it was windy, but the wind didn't cut through me and chill me to the bone. It was EXACTLY what I needed. I usually buy a large, but the medium is fitted perfectly so you can have a couple of light layers beneath it. (And, it's a cool color with a flattering cut.) This and the Rainrunner pack jacket are two of the best investments I've made. A great complimentary pair of jackets. (I need to update my Rainrunner review and rave about its perfection now that I've worn it on the trails when it was mid-30s and quite rainy.)

Worth the wait :-)

Had seen this on a runner I follow on Instagram. I saw the beautiful tectonic shift colours and loved, loved, loved it. I bided my time, trying to not want it (!!), then it went on sale. Mine!!! It's even better than I expected. Much better in rain than anything else I have-it doesn't cling to the skin, very soft. I can even run in colder temps with long sleeved shirt underneath it and it traps air and I'm warm without adding another layer. Absolutely recommend. Well made, love the pattern and feels good, too.

Best windbreaker

I have tried a lot of different running brands and this is, hands down, the best windbreaker. Super lightweight, love the fit, and it’s quiet. It packs a lot of warmth and wind blocking for such a light jacket. Love it so much I bought it in several colors.

Really holds up!

I am so pleased with this jacket. I recently fell hard while running and slid across the pavement with this bad boy on. My elbow slid and there was not even a slight indication on the jacket..no tear, pull, or anything. Well with the price!

Warm warm warm!

I bought this as it gets super windy. It’s gorgeous and very light. It does make a “swishing” sound because of the texture of the material but nothing like the rain jacket. This jacket has kept me so warm on days below freezing temps! I’m so surprised based on how thin and light it is. It was 29 degrees this morning and had on a light Tshirt underneath and I could only feel the coldness on my cheeks. Doubt I’ll ever need a heavier jacket

Buttery soft - a new favorite!

I instantly fell in love with this wind shell when it arrived. I’ve found it to be a great go to “long sleeve” for cold runs with a slight breeze or drizzle outside. I wear just a sports bra underneath and love that the fabric doesn’t stick to my skin (unless it gets drenched from the rain). It’s roomy but not baggy and doesn’t overheat on a run. I love the elastic band for the hood and feel like the hood stays securely in place with the zipper all the way up. It can stand up to a very light drizzle and stay dry, but I took it out on a run when a actual light rain started and found that it was pretty wet and sticking to my skin after awhile. No biggie since it’s not intended for a downpour but just something to keep in mind. The lightweight breathability is worth the compromise. Very impressed with this piece Janji! I had to come back and get other colors because I wear this on my runs too frequently.

Needed this

I'm very pleased with this purchase. The vapor color is so different and the jacket has a very flattering cut. I love the light weight, like I'm not wearing anything extra but I went on a morning run in 35 degree weather and it was perfect with a merino long sleeve underneath. I always size up from S to M in jackets so that I can layer underneath if needed. This jacket was a need and filled a hole in my closet for lightweight wind protection.

It's hanging on my wall just so I can admire it!

I love this jacket. I got the Sea Drift art jacket and it is so beautiful. I took it out yesterday for a run and it worked! Blocked the huge wind. I was wearing short sleeves and the fabric of the jacket on my bare arms felt really soft--not gross and cold like straight nylon does. Note--the description says it is a trim fit--that is true. But not so trim that it was tight on my big belly. If you are a larger person, you might want to get a size up. really great jacket--i am now a janji fan for LIFE.

Perfect for wind chill and light moisture

I LOVE this jacket. The print is gorgeous!! Functionally speaking : it is unbelievably light and buttery soft, but powerful in blocking wind chill by just the right amount to keep me from cooling out but also not make me all sweaty. Though it’s not a rain jacket, I’ve found it can also keep me comfy when there’s mist or such moisture in the air. Several easily accessible zipper pockets, of course. It packs down tiny and really is no bother to just take along on a run if you’re worried it might get chilly or windy. I just did a long run where I really only needed it for before and after the run, but it was no trouble at all just carrying it with me (I pulled it through those back pocket thingies of the Pace shorts). The only thing I keep wondering is whether it really needs a hood (I feel like I could do without), but I’m not going to complain about it having more features than I need. ;)
