Favorite running cap.

Best running hat for me!

I have owned a lot of running hats over the years -- Nike, Brooks, Asics -- but for me Janji's AFO Hyperlights are the best: lightweight, well-designed for heads of all sizes, and colorful. Quick-drying too. And, so far, no fading or sweat-staining. A+

Love this hat!

This is the only active hat I can find that fits my smaller head! I love this hat and have bought a few of them already. I wear them for everything! Please don’t change them!


Super lightweight and no way I can’t make it fit perfectly! Love love love this hat.

I’ve got five afo hyperlight hats. Plus a couple other Janji hat models. The afo is easily my favorite. I wear this hat for all my runs and races. It’s fantastic in hot weather. I sweat a ton and this hat somehow manages to get rid of it all, allowing it to evaporate before it all runs down my face and head. I also enjoy the ability to flip up the bill. And the adjustability is excellent (though if you have a large head, it could be a tight fit). Highly recommend.

This hat makes me happy

I originally got this hat in black to wear under my bike helmet, which is also black. This particular helmet is the sweatiest helmet known to humankind. I'm not sure of the science behind it, but this Janji hat resolves that issue! It also adds a brim to my helmet (super helpful on sunny or rainy days). And when I get to my destination, I can take the helmet off and immediately be wearing a cool-looking hat. Additional pro's of the hat include:
- super easy to wash and hang dry when dirty
- extremely lightweight
- stuff it or crush it into any pack and it retains its form
My only con's / requests for future models:
- I have to wear the hat adjusted to the max size. If it was any smaller, it wouldn't fit my head. Similar to how Janji shirts only go up to XL - might be nice to accommodate larger sizes!
- A longer brim would be even more useful (still great as-is, though)

Perfect Fit

I have a very small head, and this hat is easy to adjust to my size. I have tried many different types of hats, and by far this one fits the best. I like how it’s lightweight and it’s easy to pack as well. I have a couple of these hats now and they are definitely my go to for running and hiking, or just being out in the sun.
