Weight is about 8 oz according my fish scale.
The pix are of the sock covering my 11 ft BIAS. This is not a deep cold cover for the BIAS. I used it with an under quilt with a cover. The bottom of the cover will be exposed when you lie in the hammock. The cover works very well for wind and temps into the 30's. It does cover the top, sides and most of the bottom of the under quilt to keep out the wind.
I made it as a small, 3 season cover to take along just in case the weather changed. The material is 1.1 ripstop, dark olive 2nds from DIY Gear. There are no flaws in the material.
