I really do. Sombreros are stylish. If you’re caught out in the open and must make camp for the night, it can cover the part of your body you consider most important. A texan wearing a sombrero could be taken as a symbol of the intercultural mix of border regions, which typically results in tasty foods, interesting music and beautiful women. The sombrero has a lot going for it. But, it pains me to say, it also has some fundamental design flaws. Let’s take a closer look.
The sombrero is a headware of the classical «two diameter»- type. The part with the lesser diameter needs to closely fit the head of the user. Too often, this is not the case. The larger-diameter part (or «brim») is supposed to shield its user from the deleterious effects of the sun. It typically provides protection for the head, shoulders, torso, pelvic region and 1- 2 goats or other small mammals. So, far everything is good. Everything is static. And as long as the static fit is OK, everythig works fine........
But what happens when the sombrero is subjected to powerful acceleration, and velocity? What happens to alignment? The dynamic fit- situation is disastrous! The self-aligning properties of the sombrero is such, that users are forced to leading extremely sedate lives, as acceleration beyond the minimal will dislodge the headgear.
There are some possible remedies for this situation
1) Increase mass. By adorning the sombrero with lots of metal objects (with optional decorative function), you can improve the fit- situation, under acceleration. The added mass will also limit acceleration, in itself. But it will, invariably, lead to strain in the neck
2) To avoid a gap formation between the small-dia part, and the user’s head, a band (or «gap check») can be applied, going under the chin. But it must be perfectly matched to the throat.
3) You can augument the boundry-layer between small- dia part, and user, with an epoxy- based substance. But you’d better be sure you want to, cause you’ll be pretty much stuck with the sombrero afterwards.
Consider, in contrast- the six-pence!
It is sleek. It has a tapered nose- section. When subjected to atmospherical forces, the shape of the nose- section will generate a vertical force vector that serve to retain the headwear on the users head. This is a cap with good self-aligning properties!
