Just a little note: I've heard of people having issues with the rod...because of the "pocket" for your anatomy, the rod can only bend about an inch or so from the shaft, which means the angle might not be as expected. Also, it makes noise when it's bent (apparently). I messaged the company about putting in a solid, firm silicone core in place of a rod and they said it's an option, but of course then it won't be easily packable. Without the rod, apparently even the larger versions are completely "soft" and flaccid-feeling.
