I would like to take the credit for thinking of a gear hammock but I picked the idea up here on HF. Jacks-R-Better sells gear hammocks (others may as well) that are not full sized hammocks like the one I used.
This was a "truck in" camping trip so weight was not an issue but I do carry it when backpacking. The GTUL with straps + whoopies weighs in at 14.5oz. Just for reference the gear hammock sold by JRB is less than 4 oz.
