I bought a 12 pack over 10 years ago for half the current price ($73.49) but still worth it. I purchased 12 so I would have spares for when I broke or lost them. So far I have every pair I purchased! I wear them for all activities outdoors including running, working in the yard and riding an ebike. They fit well with the 4 bike helmets I have including Smith Men's Mission Snow Helmet which comes down over my ears. BONUS: Meets ANSI Z87.1+ standards for personal eye protection and provide 99.9% UVA/ UVB/UVC protection. https://www.amazon.com/Jackson-Safety-Nemesis-22611-Anti-Fog/dp/B00982XXJ6
