Not sure if anyone has ever thought of or posted this before, but it's commonly used on backpacks to handle the tag end of straps. Why can't we use it to bundle the tag end of tree straps that's left over most of the time . I've not tested it yet but could work as a pretty good water break too. 1-1/2 wide heavy elastic from Joann's, less than three bucks for a 1-1/4 yd. Cut at 3-1/2 in. singe ends, bar tack a quarter inch from edge, fold right side out and slide on working end of strap. Set hammock and adjust. Bundle left over strap and tuck under elastic. Positioned close to buckle or what ever adjustment you use and should work as a break too.
