Ok, it seems on scentlok.com they're only linking to their fanny packs, no backpacks. Not sure if they're going to bring them back, but I've reached out to a few backpack manufacturers to see if their packs are washable. So far, the only name brand that's washable (in a side load washer, not a top load) is Badlands. Alps Outdoorz is not. I have a Kuiu pouch that held up well in an accidental clothing wash. I've reached out to Kuiu though for the official word and will report back when I do.
