Richtorfla,
The desert camo version is made from a polyurethane coated material, weighs a ton ~54oz. which is as much as 4 regular sil tarps. I just liked the camo pattern. But it is relly heavy. And the desert camo material was only 56 wise as the sil is 64 wide.
A standard Ogee, 11' ridgeline, weighs in at 15 oz. or less, when made with 1.1 silnylon.
My first few prototypes were made with a polyurethaned digital camo and they weighed 30 oz. (pics of the "original ogee", here.)
Thanks for the compliments.
