Super durable - could be a little lighter - Outdoor Research Ultralight Compression Sack 20 L

I grabbed this to use with a 20 deg down sleeping bag and while it compressed the bag down, it wasn't as much as I would have expected. I guess the factory stuff sack does a good job. The 4 straps do work well and are much stronger than the other compression sack I tried (Klymit). I think this would be better suited for stuffing clothes or jackets. It's well made and definitely works well just not as well as I had hoped.
