We’re gonna take a shot in the dark that you hate jingling keys as much as we do. It’s not the end of the world by any stretch of the imagination, but it’s really annoying when you’re trying to exercise–even if that only means running for the bus.

One of six different leather or elastomer options, paired with a custom-designed locking mechanism that will hold up to nine standard keys.
