Not quite there

I've put it through the wringer

Got those on SAC and honestly, I would return them if I haven’t paid so little. Don’t expect to be as performant as a standard tubular 4 straps compression sack. First, you have a zipper at the opening. And zippers are less easy to close when the sack is full and uncompressed compare to a draw cord. bag is tedious and slower than standard compression sacks. Second, the buckles (2 on smaller bags, 3 on larger bags) are one side only; this will make the compression uneven. On the plus side, they are lighter than standard compression sacks, and the buckles makes getting access to the gears way faster.
