The original device will hang your pack on a tree to keep it off the ground and accessible. It is a 6-foot-long Zing-it! with a locked Brummel on one end and a spliced Titanium Dutch Hook on the other. It is entirely adjustable; weighs just 3.8 grams.
 
The larger version, 'The Big Carl Pack Hanger,' can also be a suspension extension. It is 6 foot long, 7/64 Amsteel and has a locked Brummel on the one end and a Titanium Whoopie Hook on the other. Weighs 14 grams.
 
The stocked gear is in yellow. If you dislike yellow, choose a custom colour.
