>>1974746Like the Super Cat, these are a budget option that have advantages over commercial options. Covers are only good in light rain. Heavy downpours will always find a way around a pack cover.
You stuff this into your empty backpack, load everything in, then roll the top closed. 100% waterproof, but your pack itself will get wet. They’re tough enough to last a good while, and are pretty close to the same shape as a pack (contractor trash bags are much, much bigger). Like $3 for this box.
