One is about 10.5 X 8.5
he other is 11 X 8.5
Both made from sil Poly with a lightly heavier fabric for the reinforcements. I don't know about the first (smaller) one, but the larger one, including the guy lines and the (non continuous) ridge line weigh 13 oz.
For my first gear build I'm pretty happy with them.
