Of course (sic). I LOVE to elaborate (as others will tell you...)
I already have a bright lime-yellow Adidas branded ball cap with reflective embroidery (Adidas logo), and reflective grey, edge piping. It is nearly as bright as the Ergodyne hats I mentioned above. However, the fabric is softer, more comfortable (IMHO), and can be soaked for evaporative cooling when walking on hot, sunny days. Plus, I already own it, and it is more wearable "apres-walking" in the evening, as casual wear (it is a tad more stylish).
Finally, as regards the benefits of a ball cap style hat, generally (IMHO), a ball cap is the better alternative for wearing under a poncho or parka hood. Sun hats, worn in the rain under a hood, allow water to run around the hat's brim and down your back.
But, here is a link to eBay, where the exact (including color) cap can still be bought:

BTW, I donated the Ergodyne ball cap to another Forum member for postage...
As regards sun hats, I prefer hats with broad brims to ball caps when walking in the Spanish sun. It keeps my neck in shade, reducing sunburn.
I prefer my North Face brand, ultra light-weight mesh panel hat in very soft tan SPF 50 fabric. I bought the hat in the Leon, el Corte Ingles department store in 2014, and love it! It replaced a heavier, older sun hat with less ventilation. This sun hat has covered mesh panels all along the sides and a neck cord to keep it on in windy conditions (Meseta). It can be soaked then worn wet for evaporative cooling. It rolls very small and only weighs 57 grams / 2.0 ounces (dry). Sorry, I have not been able to find it online to share with you. Also, I cut al the tags off so I do not have the UPC or other identifying information.
The Ergodyne sun hat I mentioned above (L/XL) weighs 82 grams (2.9 ounces).
BTW, the two Ergodyne BRIGHT sun hats, mentioned above (S/M & L/XL) are still available for postage to a good home... Send me a Private Conversation.
Finally, for reflective use, I always have my Leki Ultralight walking sticks with the 3M reflective tape on them. These NEVER stay home. They literally saved my life while on the
Camino Frances in 2013. I will use these poles until they "give up the proverbial ghost."
As much of my April-May Camino walking is on rainy, overcast, or even snowy days (at altitude), I perfected a wrist-rotating method of producing a flashing "arc" in the face of approaching traffic. Simply holding on to the walking stick and rotating my right wrist anti-clockwise, produces the appearance of a whirling arc (like a propeller blade). The arc extends about 90 degrees. It NEVER fails to get the attention on oncoming drivers. Try it, it works! When I am walking approaching traffic (always) as a vehicle approaches several hundred meters away, I flash the "wrist arc," pause, then flash it again. It has never failed to cause the oncoming driver to yield and move towards their left, the center of the road. Many also flash their lights at you to indicate that they see you.
I hope this helps.
