    I've been using mine doubled up with knots tied in to form loops which I hook a carabiner into. I can't say that I've noticed much stretch.

    dd's webbing does not rock at all...

    It's heavy, bulky, stretchy, it 'sticks' to barky trees (the material snags) and you have to tie it...


    get rid of it and either get a good non stretching kind of webbing with buckles (I did) or go whoopie sling (did that too , even better)

    other than that, I love my dd frontline

    dd webbing to whoopie

    today i made the webbing whoopie, works well but haven't spent a full night in it. i think the stretch will be ok and from now on very easy to adjust. i did this with a empty ballpiont and a bicicle spoke. goodluck to the one who try...

    I contacted DD about their webbing ratings and was told that the suspension webbing was rated for 150 kgs (330 #). A little on the smitely side (IMO) if only using a single strap instead of the 2 as designed.

    That figure will be their working load, 800kg is the breaking strain of the black webbing and doesn't account for knots, wear etc.

    Assuming a knot will derate the line by an average of 50%, a 150kg load in the hammock hung at 30 deg gives the webbing a little under a 3x safety factor-much less than the normally accepted 4 or 5 to 1 margin.

    Much better doubled, or even better replaced

    So...the way the DD comes configured, does it have a 300kg working load (150kg each line - even though it is all really 1 piece of webbing)? Sounds like I won't be trying to hang from just a single line - I would prefer a little higher safety factor when a 2 foot drop on my butt is at stake.

    Yeah, I'd take 300kg as the working load with the lines doubled. Thats likely to be on the safe side too.

    Thats actually much higher than amsteel blue in 7/64, so Its definitely not a worry unless you are 300kg in weight

    I think its more complicated than raw figures in real life though. There is massive friction on say a pine trees bark with a wrap round the trunk; it must take a large proportion of strain off the knot, thus not derating it as much. Good knots will also not derate the line as much.

    My original webbing must have done close to 100 nights before I changed it for dyneema, definitely well tested doubled

    I'm sure the webbing is strong enough doubled and the figures prove it, but I just didn't like it for some reason.

    I switched to no stretch webbing tree straps, and dyneema whoopie slings and it really is worth it. No only is the set up far far quicker, the lack of stretch means I get the height I want first go every time.
    The saving in weight is an advantage too, but not the main reason I opted for this type of suspension.
    Cheers
