Material: rock climbing webbing, ~1.5 ft / strap ($.36 / ft.)
These will never rip apart. They are good for at least 18kN of force.
Athletic tape the ends and you’re good to go.
I would rather work security for a Limp Bizkit reunion tour (all 48 shows) for no pay than waste 10 dollars on some poorly constructed lifting straps that will break after 3 weeks of use.
