Love the color and quality.
Recommended Face Size: Medium to Large
Frame Style: Fort Knocks
Lens Tech: Polarized
The Headbanger Fort Knocks are for everyone who knows that music rocks harder when the amps are all the way up. A deep black front frame wraps polarized red monochrome lenses, complete with a skull lens etch in the right-hand corner. Each arm features a black and red blotched base, but the main event is a “Sign of the Horns” hand grasping a wild bolt of lightning. Eruption red hardware rounds out this hardcore pair of shades—perfect for your next concert!
Designed on our durable and high-quality Fort Knocks frames, these sunglasses have a slightly wider fit than our other frame styles and provide full UV400 sun protection. Every pair comes with a red lightning microfiber protective pouch, guitar pick, and a numbered edition card.

In 2022, Knockaroud officially became Plastic Neutral—for every pound of plastic we use, we remove one pound from the environment elsewhere. But that’s far from where our sustainability efforts end. We’ve also implemented minimalist, recycled packaging, eliminated single-use plastics, and included recycled materials in our products whenever possible. There’s always more progress to be made, but we’re committed to putting in the work.
Stay Glare Aware
Polarized lenses cut glare by filtering out horizontal light waves, like the ones that bounce off water or the road. Without this glare, you’re left with a more gentle view and reduced eye strain, not to mention crisper, cleaner details!
