I am very pleased with the service I received from Biltwell. I really like the googles. I also purchased the yellow lenses and I wear them day and night. The yellow lenses helped with glare at night which was a problem for me, and they also make riding in the sunlight very nice as well. I have the darker lenses which I used before I tried the yellow, but I like the yellow better and another thing is that I don't have to carry clear glasses or lenses with me if I leave in the afternoon and won't start the ride home until after dark. Thank you Biltwell.
