Zerust has proven to be the absolute best way to protect against rust and corrosion. Molded right into plastic, this patented polymer emits a harmless vapor, forming a protective layer around metal surfaces. All Zerust products will maintain their effectiveness up to 3 years or more, so you can count on hassle free, long lasting protection.
We are a Seattle, WA based outdoor gear store with a mission to make climbing, backpacking, skiing & mountaineering accessible and enjoyable for everyone.
