Replacement for clear lens that came with helmet. The pivot broke on the clear lens, so I bought the partially tinted lens. It arrived quickly and is a perfect fit. It works great in the day. I don't do much night riding, but it is not bad, although if you have both I'd use a clear at night.
I bought the smoke face shield for the summer sun here in Texas. I bought the dark smoke first but it is really dark and if it gets too cloudy or you get caught after the sun goes down you had to ride with the shield up to see. The smoke is a good tint between the dark smoke and the clear. It probably the perfect shade. Love it.
The dark smoked shield was worth every penny. Here in North Florida in the summer riding in 98 degrees heat, this shield was so much cooler. I noticed instantly. Took a little playing with it to figure out how to attach it to the helmet. Very worthwhile.
I purchased three different shades of these and I can't say anything bad about them. The smoke offers plenty of visibility during the night and more than enough tint to keep the sun out of your eyes during the day.
