    Check with REI on the breaking strength. Best rule of thumb is 10-to-1.

    Also, if it's nylon, it will stretch. Not good.

    I use 3/8" mule tape and I've got 40 lbs on you. You will get some stretch if it's nylon climbing webbing.

    nylon= big nono. Stretches... and stretches.. and stretches. Ive dropped almost two feet over the course of the night back when i used nylon. If you want light weight, try polypropylene as it is (i believe) lighter weight than poleyester.

    I made some 20mm wide tree straps from 750kg mil spec polyester webbing for wrapping round the big old gnarly caledonian pines I regularly hang from.

    No stretch detectable and 14g/metre.

    I don't use them on soft barked smaller trees though, they mark.

    saving weight on tree straps

    This is a great question. Whats the thinnest lightest webbing for tree straps that can handle the stress and load.

    For example on strapworks.com it lists polyester webbing; the smallest is 3/8 inch. thickness of 0.040 of an inch, breaking strength 1500 pounds.

    I'm thinking further weight savings is possible by using longer amsteel whoopies and shorter webbing for tree straps. I can avoid using metal biners to clip the webbing, and be sure the toggles are light as possible.

    Let's remember that the 1" width webbing was selected to protect the tree, not because it was required for strength. 3/8" webbing may not protect a thin bark tree.
