+2 pts“You don't have to be a dick about it. I'm well aware of the capabilities of these bags. Sea to Summit specifically says [they're not immersion rated.](https://seatosummit.com/products/the-big-river-dry-bag?variant=42043827847341) Clearly my use case, risk acceptance, and budget are very different from yours. And that's okay.”
