This is a new harness based off my personal rig that I made about 8 years ago. Basically the same design except I added more Velcro & lost the lower strap.
I'll be posting a FS thread in the Cargo Hold for anyone interested in one of these.
The blue one is the old harness the black one the new set up. It is made of BREATHABLE 10 oz cotton duck, a cotton fill layer to add some weight & strength, & cotton liner. Everything has been serged & stress points triple stitched. Weight distribution is excellent & the design acts as both a girdle & helps support the lower back. I wore mine for about three hours straight on Halloween & didn't even notice my jetpack on. An option will be extra straps on the front that the cod can attach to & helps with weight distribution & keep everything in place.
