The FlexSafe appeared on a US TV Dragons’ Den equivalent, called Shark Tank apparently, where one of the “Sharks” backed the idea. It’s a portable outdoor safe, which you can strap on to just about any sort of bar, with a combination lock to keep it securely closed.
The FlexSafe’s material is slash and water resistant, with an internal zippered pocket to repel even the most digitally dexterous thief. And the lightweight design means it can fold up small for packing. Just make sure whatever you’re attaching it to isn’t too easily removed by more street-savvy shark-types.
