New Dynemma Tree huggers

[ikemouser]

Right now tree huggers are the heaviest part of my suspension, replacing them with something from here should save me at least an oz or two. You just have to sew a loop in the end.

group buy?

I love Dynemma! Could you take two "tails" and do a double marlin Spike? I have never tried it, but in my mind it would work. Dynemma is slippery so I'm not sure. Just an idea that would eliminate the need to even sew.

I would be up for hosting a buy of this and picking up a few rolls for stock. Mite make it easier to hit the minimum order qts.

Could be expensive based on the price in the link below

hangnout,

That stuff's tubular so it's heavier as well

Ike: as per the thread over on BPL I've emailed Sturges to see what they say is their lightest webbing that is @ 1 inch wide. Won't likely get an answer until Monday. Did you find out anything?

I've been searching off and on over the past year, and have not yet found any stock HMPE webbing which seems worthwhile. It is available and it is lighter than other materials but it's generally much too strong (i.e. not as light as one might hope).

With a width of at least 1" and a breaking strength similar to alternative materials, it will be *very* thin, probably requiring a custom order.

Here's a brief comparison:

- lightest 1" HMPE I found: 16.2 g/m 1140 kg (0.52 oz/yd 2513 lbs)
- AHE polyester camo: 19.8 g/m 544.3 kg (0.64 oz/yd 1200 lbs)
- MIL-W-43668/A-A-55301 Type III nylon 1”: 15.5 g/m 453.6 kg (0.5 oz/yd 1000 lbs)

Anyone who needs enough webbing that the difference in weight is significant may do well to rethink that suspension and use cordage instead. The amount of webbing needed to protect trees is relatively small.

Because HMPE has almost no elasticity, a suspension made entirely of HMPE is vulnerable to shock loading, which is good reason to introduce some elasticity (shock absorption) into the system.

I use a basket hitch for strength efficiency, and my tree slings are no longer than necessary, so even with nylon slings, elongation is relatively low.

For my purposes (used in basket hitch with an angle of 90° or less and a load of 160 lbs in the hammock), the MIL-W-43668/A-A-55301 Type III nylon 1” offer the best solution I've found so far.

Thanks Albert that was a really informative post and confirmed what I suspected about lighter weight dyneema webbing which is that it is probably not made a weights/strength ratio that would offer enough weight savings to make sense for tree huggers or hammock webbing in general.

"Because HMPE has almost no elasticity, a suspension made entirely of HMPE is vulnerable to shock loading, which is good reason to introduce some elasticity (shock absorption) into the system."


I hadn't considered the static shock if that's what it's called. Seems like that would be even worse in a cuben or polyester hammock.

you could just make straps from dyneema fabric

[warbonnetguy]

yeah, i doubt it's very light either. only one way to find out.

Found out nothing. Hope to hear back, i thought it would be lighter, seeing as dynemma has (according to the site) one of the highest strength to weight ratios, perhaps too much strength then?
