It's kinda unhealthy to be admin on a tool-website with over half a million articles
. Anyway, saw this cap (for 15$) and had to order it.
UVEX u-cap sportI was a bit surprised how comfortable to wear it is. Its also rather light. It is fairly stealthy from the front except being a bit taller than your usual baseball cap. The bright UVEX logo is also a bit of a give-away. From the back you can easily spot the plastic shell.
It does not replace a helmet, but it is certainly an option whenever you won't wear a helmet but probably should. Like cutting the branches of your tree. I also see this to be a choice cap for security guards that don't want to wear a helmet but still would like to be offered some protection against thrown beer bottles. It is also great for tall people who bang their head a lot
