Query: Excellent, Affordable --- NO FOG --- Goggles

I'm an adult, weekend, beginner dirt bike rider that rides around trails with my kids. I needed a pair of inexpensive goggles that would fit comfortably over my MX helmet and protect my eyes from dust and debris. WOW - these goggles are perfect. I purchased two pairs of cheap goggles off ebay for my kids. They always fog up and are not very good. I even purchased some anti-fog spray from Amazon to spray on and they still fogged up.To my surprise, these Raider MX goggles did not fog up one time during a 4 hour ride. No spit, No anti-fog spray, no constant wiping. Just wear and go. Wow. So I gave these to my son and now I need another pair for myself.Longevity will be the issue with these goggles. The lenses will probably scratch easily. But the price is right and I'm very happy with the purchase.
