Print Story - Star Cover

As part of our American Southwest Collection, this print was designed by Santa Fe-based multimedia artist and pro mountain trail runner Christian Gering. Proliferating a single star (represented by a four-pointed directional cross) into a sky pattern, this joyful composition symbolizes the never-ending fabric of time and represents a connection across generations to ancestors who guide us, lighting our path.

Print Story - Under Cover

As part of our American Southwest Collection, this print was designed by Santa Fe-based multimedia artist and pro mountain trail runner Christian Gering. ​​A monochromatic, reflective version of the “Star Cover” print rotated on a 45º axis like stars shooting across the night sky. This design represents a connection across generations to ancestors who guide us, lighting our path.

Print Story - Summit
design evolved from a conversation around "mountain logic" — how a runner forms the link between earth and sky through their ascent and descent of vertical terrain. Look for the ladder in the print, symbolizing that connection and transcendence.

Print Story - Joy Champaka

As part of our Chennai Collection, this floral print is designed by Chennai-based textile artist Kashmira Baheti and is based on a magnolia flower, or champaka — commonly known now as the joy magnolia and revered in Chennai for its joyful fragrance.

Print Story - Pop Champaka

As part of our Chennai Collection, this floral print is designed by Chennai-based textile artist Kashmira Baheti and is based on a magnolia flower, or champaka — commonly known now as the joy magnolia and revered in Chennai for its joyful fragrance.

Best hat!

I love this lightweight, comfortable cap! It's breathable, easy to travel with, versatile, and comes in so many fun patterns. The bungee strap on the back makes it really easy to adjust while moving or running. I have this in spray die and joy champaka designs, but plan to get a couple more!

Great Hat

I've run in trucker hats for a long time but wanted a hat that had a lower profile and with a squishy brim. This hat is super comfortable, runs cool, easily adjustable, and is so light it barely feels like it is there (until it rains or the sun would be shining in your face). The Under Cover print looks great!

Great Hat for a non-hat wearer

I don't usually like hats, let alone while I'm running. But I have a big trip coming up and thought I would stock up on the right gear. The AFO cap was a perfect addition to my setup. It's super light, bunches up easily into a pocket, dried off quickly, and the bill easily pops up and down when I need it to. Highly recommend.

Love this lightweight cap!

Great even on the hottest days in the summer. It fits well and you can even forget you're wearing it. I will get others!

best hat out there

This hat is amazing. Lightweight, compact, and fits all head sizes without bunching up in the back when tightened. This design is so well thought out. I have one in black and spray dye and just bought my 4 1/2 twin nephews two as well. I let them pick the and they decided on the joy champaka, and pop champaka. They love these hats and wear them all the time. It's also been good for finding them at a packed park. I just look for the hats, and they're keeping their heads cool from the sun with out the burden of actually feeling like you're even wearing a hat.
Also is perfect for wearing under a cycling helmet. So many awesome uses for this light weight hat.

My go to running hat.

I love this hat; it's my favorite running hat. I own three (2 in black and 1 in roayl blue). I wore this hat for a marathon, 1 mile, 5k, and the brim holds up unlike the new Patagonia duck bill hat's which lose their shape and start flopping. I hope Janji brings them out in some more colors like mango orange.

Advantages: Cool design, fit looks good and comfortable, neat design for adjusting the tightness, light weight fabric, brim is firm, dry up fast (wow), has the right size, and do not smell (I have worn them three days in a row for my runs; I air dry them after my runs by placing them in front of a fan).
Disadvantages: Only two - Keep the bungee away from your cats lol, wearing it backwards might hurt your forehead since the bungee's might dig in.

Hyperlight Cap

This is my only worn cap now since receiving. The size/weight/material are top tier. These days I like products without any visible logos and this hat has a nice subtle logo design on the side. All I could hope for would be a light grey and a dark grey version to get added. Then I could have the perfect minimalist 3 hat rotation <3

Wish I could have kept it

I LOVED the color and fabric and fabric pattern and tightening mechanism on this hat SO much and wanted to keep it so badly but it just was not big enough for my head. Needs to come down farther on the sides. SO bummed I had to return it. Could have been a favorite.
