PROVEN SINCE 1971
Made for hunters, by hunters.
You did everything right: wind in your favor, scent spray on your boots, hours behind the bow all summer. And the deer still hung up at forty yards, staring at something you couldn’t see.
Atsko spent decades chasing that exact problem, because we’re hunters too—and we got tired of gear that almost worked. ZERO exists because scent control alone isn’t enough, and UV alone isn’t, either. It takes both—built by people who needed it to work before it was ever a product.
HOW IT WORKS
UV concealment, explained.
A deer’s nose isn’t the only thing you have worry about on the hunt—their eyes are able to pick up the invisible UV glow on your clothes—like brighteners most normal detergents leave behind on our fabrics. And when sunlight hits them, your visibility goes up.
The Original U-V-Killer® works to block UV light from ever reaching the brighteners. No UV means no glow, even on overcast days. Even at dawn and dusk.
ZERO N-O-DOR® Oxidizer
Don’t just mask your scent.
Eliminate it.
Other scent products made for hunters simply mask odor with a stronger smell. The ZERO N-O-DOR Oxidizer is different: it oxidizes odor-causing molecules at the source, breaking them down so there’s nothing left to detect.
