care instructions

Hand wash for optimal longevity or machine wash on cold, delicate cycle

Hang dry for best results (it dries fast!)


The Zephyr Runner fabric uses a PFC-free water repellent finish on the fabric, which unlike standard DWR's, is not made with harmful PFC's and therefore will not release any perfluorinated chemicals into the environment from wear or washing.

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

Not Very Low Profile

It's called a low profile hat, but I have to say compared to some of my other running hats, this one might as well be a trucker cap. Outside of that it's pretty comfortable, breathes well, and appears to be well made, so I'm not going to return it. However, caveat emptor - not as low profile as other actual low-profile hats.

Great running hat if you don’t care what it looks like!

I love this hat. I hardly notice that it’s on my head. Very light and blocks the sun. My only complaint is that it looks hideous on me. It’s just not a flattering hat, but I like the function of it so much that I wear it anyway. I’d love to see Janji come out with sone new colors/ prints in this hat.

Awesome hat!

This is one of the only hats that I have ever liked for running! It has zero bounce and I totally forget that it is even on my head. I also love that it is adjustable and that I can shove it into my vest, as well. Very very light. Feels like I am wearing nothing, but still protects me from the sun!

New favorite

Everything I want in a hiking cap. Lightweight, no frills and comfortable. Simple, light, and good looking. Love it.

Morgan Sjogren
I wear this hat on every run!

This hat is so light I do not even know it's on. I wear it with my hair pulled through instead of a ponytail holder which keeps my hair out of my face, protects my hair from damage and keeps my face out of the sun! It can easily be tucked into a pocket or bag without taking up much space.
