Remember when your Mom tied strings to your mittens, so you wouldn't lose them when you took them off? These are pretty much like that, but for your gear. Great for keeping small lights, cameras, tools or other accessories close at hand. Coil Lanyard extends to 36" when released. The Octo holds gear close and releases with a quick pull. Retractors use an extending cord to keep items tethered and available. Locking model extends to 30" and Mini extends 20".
