Review: Love it! - Very heavy duty! I need the elastic to make a few EDC loops on my belt, and it is a good tough elastic. It holds my heavy leatherman surge right agaisnt my belt, no problems. Made another 2 loops to hold my baton and pocket knife against my belt and it continues to hold it securely with no issues. I can think of a million uses for this. For instance making a small elastic loop to keep my rats tourniquet together or other gear in place. I plan on stitching a few straps of it to my edc bag so it can hold more gear securely.
