in my experience Dyneema/DCF/Cuben Fibre (all the same thing) packs just as small as 20D SilNylon.
You can stuff it, but it's hardly an effort to fold something up in the morning.
The benefit is its durability, especially in stretch-shear situation.

The same size tarp from Yama in Dyneema/SilPoly is:
Dyneema: 20cm x 15cm x 5cm / 156g / $295
SilPoly: 13cm x 18cm x 5cm / 255g / $110I just don't see why anyone would buy the Dyneema version, personally. And I know it sounds silly, but IMO rolling/folding something up in the morning IS a pain, when I can just stuff the entire thing without any concern in my outside pocket.

I thought Dyneema wasn't supposed to be folded, at least not along the same seams all the time. I have a Cuben bivvy that gets mostly folded and a little bit stuffed most of the time. noideadog.gif

Not when SilPoly exists. There's little to no use case for dyneema in tents IMO. Its slightly lighter than SilPoly and SilNylon, but its huge and can't be stuffed into a pack like SilPoly and SilNylon can. I'm all about pack size.
Tarptent Moment DW Li (Dyneema) = 745g and $639.
Tarptent Moment DW (SilNylon) = 973g and $349.
I'm all for spending stupid amounts of money to reduce pack weight, but its just not worth it for that small of a weight saving IMO - especially when you can't just stuff a Dyneema tent into a pack.
