UTVzilla.com, just bought their glass with bottom flip up vents and love it. Have had 2 expensive poly windshields and the just don't hold up with all the dust. Glass windshields attract less dust than a poly as well.
I have glass and it’s great when it’s cool or raining. I’d love a half windshield when it’s hot out.
I run the scratch resistant poly from super atv. I wanted glass but with 100+ Temps and black metal roof, there’s no way I can even ride comfortably with a glass one with little vents. I need a flip up completely.. I usually just soak the windshield, then add soapy water then rinse with my power wash, no issues with scratches. There’s anti dust sprays that keep dust off as well..
