Is there anything needed for pack-out?

No. Although it is recommended to have a thermometer to monitor the temperature and some filler material (newspaper, bubble-wrap, etc.) to prevent contents from shifting.

Can a Cool Cube™ be locked?

Yes. The large cooler can be locked with a small, steel padlock. The small and medium coolers have double zippers that can be fastened together with a small, cable padlock.
