The Killerz are an unbelievably awesome pair of sunglasses/goggles. It’s foam lined for extreme wind protection, made from a TR-90 nylon frame which is ridiculously durable. They are available in foam lined goggle style and regular non-foam lined styles. The lenses are available in polarized amber or brown, polarized smoke or grey, transitional clear to smoke, and transitional yellow to smoke as well. Simply put…You’ll love them. It’s killer!
