Love the shirt

Very light and breathable. Sharp colors and design. Rides a little looser than expected. Maybe consider a size down if you want it to be more form fitting.

The lightest top ever

Great top. It's the lightest top I've ever worn. It might run just a little large, but not by that much.

Massively moisture wicking and very lightweight

Wore this to my half marathon race day. You're getting a very light top. Even after 13 miles on a summery day I did not feel soaked in sweat. It was light, breathable, and honestly looks great.

Vibrant colors and soft fabric

Very light and comfortable fabric. Wicks sweat and drys quickly as you go.

Survives the Sufferfests. Looks Good Doing It.

This isn’t just a singlet. It’s a war flag for the miles ahead.

The Janji Pinnacle Ultra in Flower Trippy tackled Florida heat like it was born in the sun. Sweat? Gone. Fabric? Barely there. Breathes like a whisper, moves like a second skin. And the color? Straight from the fever dream of a dehydrated genius—wild, bright, unapologetically alive.

Mid-run, I swear I saw a talking armadillo nod in approval. Might’ve been the heat. Might’ve been the truth.

Bottom line? This thing’s ready. For whatever weird, gritty beauty the trail throws next.

Not Bad

Does collect some sweat, but lightweight.
Could really use an XS size for "Men's" cuts.

This is small?

I joined the Janji Collective and began ordering items because I long ago fell in love with a Janji running singlet I purchased at my local Pacers Running shop.

That first shirt, size small, fit perfectly, felt perfect, and looked perfect. Unfortunately, after joining up and placing my first order, I received a lovely looking singlet that was part of the Moroccan collection - I was born in Morocco and spent part of my childhood and adulthood there, so was attracted to the shirt’s Moroccan design - that was described as a small but fits like an oversized Hawaiian shirt. Seriously. Acres of space. Enough material for a pup tent.

I hope that Janji will standardize its sizes so that we know what we’re getting when we order and pay for something. This time I lost 80 bucks. I didn’t totally lose it, as I’ll wear the shirt occasionally, but not with the enjoyment that I had hoped.

Oh, and I can see that the “how does it fit“ scale included with this review ranges from “runs small“ to “spot on“ but doesn’t allow for anything in the “much too large“ range. That’s the one I would choose.
