sustainability

The first rule to making something sustainable? Build it to last. This top is built to endure the rigors of serious wear. We made it out of our AFO-Vent fabric — a durable nylon that is lightweight yet tough, abrasion resistant, odor resistant and will retain its shape. All trims are minimal and low-profile to reduce weight, fuss and stress points.

Our AFO-Vent fabric is also bluesign® certified meaning it is free from harmful chemicals and is fabricated in a way that meets a high environmental standard.

My fav

I got this in Jasper! Love the color and the fit. It’s very comfortable for spring. Have not tested for hot weather yet! But I am going to get the tank top for sure! Love this material

I love this top so much!

This top is perfect for colder months either as a layer or times when it is to chilly for bare shoulders. I often wear it under a hydration vest, without any chafing. Thank you Janji for making it!

Very comfortable, no chafing after long runs.

Great technical top

My only gripe with Janji is that they make the shoulders on women’s shirts so narrow. I’m 5’8 and very lanky with broader shoulders and the tops fit weird. I wish you guys could extend the width just a smidge. <3

Lightweight & Breathable

At first, I wasn't sure about the sleeve length. But after running around - I didn't notice that it was slightly longer than most of my shirts. I wore this on a pretty warm day and it was great! Light, breathable, comfortable, and really feels like it can hold up! Also...the Jasper color is so nice!

popeye problems

This shirt is indeed very light, and softens up mid warm-up, so two thumbs up for the description. Unfortunately, the grasp on my biceps is rather intense; it's much too tight around the arms. While this is certainly not the first time I've encountered this particular fit issue, and probably I will ask a tailor to widen them for me, I had hopes this fit would better accommodate my version of an athletic frame.

Not My New Favorite

As a heavy sweater I’m always looking for different lightweight fabric options that wick away sweat and dry quickly. This shirt just didn’t do it for me. From the moment I put it on I got a little worried. I felt like I was wearing a tarp, but wanted to give it a fair shot. As I got more and more sweaty it started clinging to my skin which I wasn’t a huge fan of. 3 stars since I love the dusk color and the cut and sleeves on this shirt are very flattering. I will say that I thought the shorts in this same fabric performed very well and I was impressed by those. I will probably use this shirt on shorter easy runs in mild weather mid-40s-60s.

Comfy, but terrible for hot humid weather.

I wanted to love these shirts. They fit and feel great. However, they are horrible at wicking sweat. I live in Florida so even my early morning runs are hot and humid. I was excited to try a new shirt I thought would feel light and cool, unfortunately this isn’t it. My sweat just saturates the shirt, making it wet and heavy. I’m sure they’ll be great in fall and winter though.
