W's Zephyrunner Wind Shell

Bought this for a 100M fall mountain ultra and it did not disappoint! I'm petite and the small fit perfectly with just enough space in the arms for mid-layers. It's not too bulky or hot and packs down very compactly in my race vest. This is definitely a gear staple and the color is beautiful!

I love this jacket! I wear it everywhere and for everything. Very comfortable and fits very well.

I love this jacket so much. This was my first Janji purchase. I love the fit, bright color scheme, the performance in cool weather. I am not a runner, but it works for walks and hikes in mild SF Bay Area weather. I am 5’3.5” and weigh 200 lbs, 38J and apple shape, and the XXL is a perfect fit. I hope this review is useful for the larger sizes shopping this brand as most of the reviews so far are for smaller sizes. I appreciate the range of sizes available.

Love it! The techtonic shift pattern immediately caught my eye and I “watched” this jacket for a long time (did I need another jacket?). I typically don’t like hoods on my jackets but because it is so light, I almost don’t notice it at all. I’m usually a small or medium and decided on a medium. It has enough room to have layers underneath if needed but not oversized. I’m so glad I finally made the purchase.

I love this jacket. First, it's beautiful. And the fabric is light and doesn't make any weird noises. It's perfect.

Literally in LOVE with this windbreaker! I’ve gotten so many compliments on the Sea Sky Cloud color and the Small fits me great (I’m 5’4” and about 145). I’ve loved it for running, biking, hiking, anything. It’s a great lightweight spring piece and I would highly recommend. If you’re on the fence, buy it!!

This is hands down the best running jacket I own. It's incredibly light weight, blocks winds up to 15-20 mph, and is yet still breathable. My only request is that there be some way to roll up and secure the hood when it's not in use.

My usual complaint with lightweight windbreakers is a lack of pockets. This one has three *zipped* pockets. The size seems a little larger than my (also size large) Janji rain jacket, but that suits me. The rain jacket sometimes rides up around my waist, but this shell flares a little more at the bottom so it keeps me covered. I wore this with the All Day long sleeve underneath on a run on a blustery 50 degree afternoon, and I was as comfortable as I could wish the whole time. The pockets carried my chapstick, a pack of tissues, and my keys.
