Does anyone wear a non traditional helmet... like perhaps a bmx helmet or some other alternative?

nope not me.

Nope.

Nope.

I will wear this one on the MUP but not on the road.

yup, from time to time

Why? Helmets are so inexpensive these days, relatively speaking, that it can't be a budget thing.

No... I was just wondering...

perhaps a mountain bike helmet? you probably want to remove the visor if you want to see in the drops.

bmx helmet..um..not sure how well the vents works

I was actually going to buy a mountain bike helmet until I got a more expensive bike and then I reasoned, "F it, if I'm going all out, I might as well get a proper helmet - the most important thing for my only brain".

Plus, the Giro Saros feels so good...

Is it wrong to kind of like this?......

No. But you gotta wear his whole getup. Kinda Flash Gordon-like.

I wear a giro indicator. I like it. I think it's a mtb helmet

It is, but the visors snap off right? If it works for you, perfect. I use the Giro Ionos myself.

What's the design/purpose of the visor? Never done any mtn biking.

On the road, glasses work fine... never had the desire for a visor.

I'd think similar on dirt trails, even more important to have good quality shades for protection from all the lose terrain those in front of you may throw up.

Supposedly to keep branches out of your eyes. IME they also help with rain a bit.

only some models of giro/bell helmets come with the detachable visor.

giro rift is pretty good.
