Stealth Glow-Vis offers the popular color of low-vis green with a unique UV reflective coating that appears to ?glow? in the sunlight for better visibility and ability to watch your line?s movements. Since UV cannot penetrate water, the low-vis color will continue to be less visible to ?line shy? fish and disappear in low light conditions. Fluorescent brighteners illuminate line above water. Low-vis green disappears below water. Enhance ability to watch line and detect bites that may not be felt.
