Heads up — AFO-Vent may feel stiffer than you're used to

This fabric is more structured so that it won't ride up or pill from lots of use. Expect it to soften as you sweat throughout the run.

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.

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!

Almost perfect

I feel the Janji sizing is a little off. The fabric is amazing - no improvement needed. The small fits a bit tight in the chest and the medium is too big. Somewhere right in-between. I am a very standard size S or 6. Janji seems more like a 4 in the S. Also the fabric is not cut in the stretch direction. So it goes on without any give. Hope this helps! I absolutely love the prints! Oh and longer shorts - 5” would be a great option!

It’s just an ok top

This top is very overpriced for what it is. I would have returned it but the company charges for return shipping.
