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.

Best Athletic Shorts!

At first I got these shorts as a runner, but then I started wearing the lm to hot yoga and AMAZING. They don’t stick and dry extremely quickly. I have 6 pairs and love each one.

Solid Tank for the Heat

I don't normally run in tanks, but decided to pick this up for the hotter summer runs. Apparently I've been missing out, as this is now my favorite warm-weather running top. It's not overly loose and doesn't bounce around, but still remains breathable and weighs next to nothing.

Might be better than the AFO Singlet

This new fabric for sure has a unique stiff feel to it, but I think it's one the best performing pieces Janji has put out. Sweat does not make this top stick to you as easily as the singlets do; which you can feel while running and cooling down. All while making it easy to doff for shower time. The snugger fit is actually more accommodating for my figure and is not tight at all. I also feel like this new fabric gives it a little bit of wind resistance, but maybe that's just me. Overall I'm looking forward to seeing how Janji moves forward with AFO-Vent, and will be slowly replacing my old AFO Singlets with these.
