These K-T Extinction Fort Knocks feature a matte Cretaceous-Paleogene exterior frame with a hazy dust-cloud interior, gold hardware, and polarized yellow fireball lenses with a fossil lens etch. Designed on our durable and high-quality frame, these sunglasses have a slightly wider fit than our other frame styles and provide full UV400 sun protection.

Every pair comes with a bolide impact protective pouch, a hand-numbered edition card, and a 2-inch fossil dino skeleton to remind us...that even this great species was subject to mass extinction.
