For non-hammock users, tree straps are webbing (inch or wider) with end loops that protect the tree's bark instead of using thin rope that could gouge the bark.
Why has no one started making UL tree straps from belts of high bias Cuben fabric?
Adequate strength would be from using several inches of width of the stronger, high bias Cuben. Is it the liability, the lack of a market for $$$ SUL hangers (hammock users), bonding strength for the loops, or tear strength of the loops with tiny Amsteel cords run into them? When you have lightened all of the other parts of a hammock system, often the tree straps are the heaviest remaining item.
Would silicon tubing in the end loops solve the abrasion problem from the 1/8" whoopies? If the bonding surface was several inches both directions, wouldn't that be strong enough?
Yes, I could have posted these questions at HF.
