The packable backpack for when the weather means business. Roll top plus a zip, seams fully taped inside, and it stuffs down to nothing in your travel bag until you need it. This is the let's-go-to-Thailand one.

The packable backpack I'd reach for most of the time. Simple, light, weatherproof enough, with a nice pocket up front and a quick-access stash on the top back. It disappears into your travel bag, then becomes your daypack on the other side.
