Technically, this didn’t fully work as I doubt it’s still waterproof, but Dang has this thing done its job. This sack holds all my sleep gear plus whatever else I can an cram in.
It never, ever complains. In a 13l sack I can fit: tarp, poles, stakes, down bag, bivvy bag, sleep pad and pillows and a bit more.
This bag is mounted on the front of my bike, so if I take a tumble it takes the brunt. Even with sharp things inside, the bag has only developed a few minor holes, easily patched.
Super pleased with this.
