Great lightweight jacket.

Love this jacket for cold weather runs. Toasty yet breathable. Had the prior version and this one fits a little baggier, but still true to size.

Great in the cold

This arrived in perfect time for the cold weather hitting in Chicago in early December. It is really lightweight but actually very warm. I was able to run in this with a single layer underneath and feel comfortably warm on a day when the windchill hit -9F on the lakefront. Good wind resistant capabilities too and fits well. Snug without being tight or feeling constrained while running.

Perfect Jacket for Cool Runs

I’m located in Northeastern Pa. This jacket has been perfect for the cool fall runs. Even the cold winter ones with layers. I’ve been very happy with it.

Great, Great Jacket

This jacket is perfect! I use it for hiking, my daily three mile walk, and everyday use. Three zippered pockets and 40 grams of insulation complete the package

What a great jacket

First use was for a bike ride, and I was suitably impressed with how it kept me comfortable while riding. Have used it on a number of runs lately, with varying distances and tempos. It did not disappoint - this one is definitely worth it.

Perfect jacket for so many occasions

I'm not one to run in a jacket like this, but for practically everything else I do in my day, this is my grab and go! Lightweight but warm, compactable, and makes me look like the coolest dude wherever I am!

10 out of 5 stars!!

Ultra light, ultra soft, block wind and light rain, great weight to warmth ratio, will want to keep it on all the time, but one size bigger to fit 2-3 under thin layers in very cold. Otherwise, only need an ultra light 1 layer for cool and cold days. The reflective snow leopard print is fantastic!! I have two of these jackets. One medium and one large, so I can fit several layers for coldest days with the large, and fit 1-2 very thin layers with the medium. Exceptional jacket! Definitely one of Janji’s best overall products. Consider the snow leopard reflective. Very cool, unique, and great looking.
