Two issues-both good.
First-working with Jimmy Neutron and Mrs. Neutron to dial in a hammock fitted to me. We tried one longer and one shorter....so I saved weight in material and got just the length/width needed.
Second-the loss of weight with a dialed in hammock left little room for 'scootching error' through the night, e.g. sliding off the hammock. The Hangnout mod allows for scootching error.
Something beyond this though...it just feels cozy having the formed box-instantly took me to that happy Blackbird place.
Now the question----please Hangnout----what was the weight penalty for the mod? My best guess was 2 ounces.
