I recently purchased some 1.5 inch poly webbing material to make a longer set of tree straps. Upon returning home I noticed that my old straps and my new material are different, they are the same width, but the weave of the material is different. The old straps resemble seat belts while the new material resembles..... I can't think of anything off hand.

Old Strap

New Strap

I am wondering if this new material will hold my weight? What should the break strength of your tree straps be? I don't really want a sore butt if I don't need one, but I guess sometimes experimentation is all there is.
If you have any answers please reply. I am going to go ahead with this test, to see if the poly material will work, or if I need to get the nylon webbing.
