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.

Like air

I live in AZ so naturally swear a ton when I run. These are amazing to wear for my long runs on the trail and fast/back/packing. Moisture wicking and airy!!! It feels like I’m wearing nothing but provide a barrier between my skin and my pack. On hot days I’ve soak the shirt completely in creeks and it provided such cooling relief!

lightweight top

This tank is my favorite for working out, cycling, and yoga. I wear it with the afo shorts for long hikes and it feels like you're wearing nothings. Dries super quick if you get it wet. All around amazing quality. My only complaint is I wish they made more colors!

Im a Janji covert!

This tank top is the best. I just went on a long run (8.5 miles). And while it did get wet with sweat (no way around that I don’t think), it didn’t way me down at all and I couldn’t feel it. I’m so amazed and impressed with janji and there innovative and nice looking clothing and gear. I also bought the sling bag and that has been a complete game changer when I’m doing a short trail run with my dog and need to carry some water for her).
I got an xs and it fits perfectly (I’m a small chested/petite person). I would size up if you have a larger chest. Gonna come back and buy all the colors (if my wallet will let me).

Best tank ever!!!

Lightest more breathable tank ever. Feels lightweight even when its covered in sweat. No seams, doesn't rub anywhere.
5'8" 155 - M fits great

Will be buying more

This is one of the most comfortable and quickest drying tops I have ever owned! I absolutely love it. It is a bit long and spacious, so consider buying in a size smaller than usual. The material is like paper, so nice.

Light & Airy

I live in a really hot climate so I was excited to try this tank. I love it, it’s super light and any breeze goes right through it to cool me down on my run. The fabric is a little stiff, as other people have noted, but it doesn’t bother me at all. It’s just so light and airy and it makes running in the insane heat much more tolerable.

Love the fit

I like that this is a basic piece that I can grab...and it's fitted enough, but also has room...no under arm rubbing, lots of space without feeling "too big". Plan on grabbing some other colors, too!
