Excellent product but - Wiley X SG-1 Frame Only, No Lens

You really have to work with the retaining cord. They need to redesign a bit. Basically you need to use needle nose pliers to get it on the temple/ear pieces. Retainers tips need to be enlarge. That's the ONLY complaint, otherwise they are a great product.
Pros: Durable, Perfect for Motorcyclists
Cons: Retaining cord EXTREMELY DIFFICULT to install, relatively expensive.
