No matter what your purpose, if you travel, this is undoubtedly one of the most useful and secure travel locks available. Remember your combination and you won't have to learn, as I recently have, just how secure this lock is! If you are a backpack traveler, I think you will find, as I have, that this lock is capable of bringing together many zippers, combining them so that the one lock will keep your bag securely shut. The cable is thin, wiry, and well covered.

Enjoy!
