Love it.
It slightly diffuses the air, but most importantly stops all the bugs/rocks/etc, from hitting you in the face. Wife hates getting gnats/bugs in her hair.
I got pelted in the face w/ bees one day and the wife was laughing at the yellow pollen dots left on my face, so I purchased it.
For night rides, it's a must. Every flying insect known to man is out....lol.
I run with the soft cab rear window, so we don't have any swirling air/dust.
It's a soft feeling mesh like in a screen door, but stronger. The sides feel like a divers suit with heavy duty zippers.
I've beat the crap out of it w/ tree branches & power washer and it's still like new.
