One of my pet peeves about being able to visit fantastic, tropical beaches here in the Philippines is the lack of lockers to put my stuff while I'm out snorkeling, swimming. I don't always go with other people who can watch my stuff. But now I have this Loctote bag, which solves the problem since it's extremely hard to get into and is made to lock to any permanent fixture. (pole, fence, table..)
I can also lock up my main valuables in my hotel room while I'm either out in town or asleep and happen to have a new 'visitor' in my room for the evening. :) Here is the un-boxing video of when I got my Loctote bag..
