Decent goggles at reasonable price point - Body Specs BSG-3 Interchangeable Lens Sunglasses/ Goggles w/ 3 Lens Set

I have used these goggles for a couple weeks now - my observations:

Positives -
Great customer service from Body Specs. I had some issues with changing lenses and they were very responsive.
Lenses are high quality
Seal appears good - haven't tested in adverse dust conditions yet
Product is very lightweight

Negative -
The foam seal is fragile and feels like it would easily break
The seal doesn't positively lock into the goggle frames - they separate at inconvenient times

Bottom line: For everyday use or a day at the range these are adequate and a good deal price wise. If you need goggles for more rigorous use - LEO/Military - you may want to bite the bullet and pay a little more for a more robust set of goggles
