I slipped the biking helmet on my head and strapped it securely beneath my chin. It fit snugly so it couldn’t fall off in the heat of battle. I could do a flip (if I could do a flip) and the thing would stay stuck to my head. I’d superglued dozens of Click-It lights all over the surface of the helmet. Brackets stuck out several inches from both sides and the rear, with spelunker lights attached, pointing downward. I swept my arms out and took a deep bow: Presenting the MacHalo!
