So, you can see that a 30D silnylon tarp will weigh less than half of your hex tarp for the same size tarp. Pack volume will also be about half.
That sounds awesome but when i look at hennessy's website it says my current setup weighs 23 oz and packes to 3.5" x 11". The same tarp in the 30d material weighs 18.6oz and packs to 3" x 10", that doesnt seem like that much of a difference to me...
If i could get a tarp to be as big as my hex and still be able to pack it in my hammock bag that would be unbelievable, but currently the pack for my hex tarp is bigger then that of my backpacker hammock + stock tarp. That just seems silly.
