The Tarpworm is beyond light. It not only is a simple way to tie out your tarp, it also has a built in tarp tensioner. Just simply stake out your tarp and then pull the cord and loop it around the tail. When you want to release it, simply pull the cord and it releases your tie-out. Weighs 1 gram. Made by Dutchware.
Comes with a shock-cord loop pre-attached.
