Wait—what’s lanolin?
Lanolin is a waxy substance that sheep naturally produce to protect their wool and skin from the elements. Think of it as nature’s own waterproofer. It’s incredibly effective at locking out moisture, resisting salt spray, and keeping surfaces lubricated and protected.
We source ours from New Zealand, where sheep live in some of the world’s wildest outdoor conditions. That means the lanolin is extra potent pure, high-quality, and built to perform when things get wet, muddy, or salty.
