The Osprey Straight Jacket Compression Sack is a storage sack for backpacking. The Straight Jacket comes in four different sizes, all with a rectangular shape for packing into your backpack with efficiency. The large zipper opens wide to stuff and jam sleeping bag, extra layers, and more inside, then use the dual straps (three straps on the 32L) to cinch it down smaller than what you started with. The water-resistant fabric is a 40D nylon ripstop to protect the items you have on the inside. The Straight Jacket and it's seams have been waterproof coated, but not the zippers so I definitely don't recommend throwing this into a river. Your stuff will get so wet.
So sorry, but only 4 items are allowed for comparison, so we're comparing the first 4. I blame the gnomes and so should you.
