I use the TravelSafe to secure small items while traveling, as it can be padlocked to something immovable to prevent the removal of the contents while I'm doing something else. It is a large enough for most small digital cameras, wallets, passports, or anything as large as a revolver with a six inch barrel. The bag is lined to protect items inside, and the stainless steel net between the fabric layers prevents smash and grab tactics for whatever is padlocked inside. It is small enough to roll up and stow in a briefcase, pocket or purse, and can be deployed in just a few seconds. The stainless steel cable that is used as a drawstring doubles as the security device, securing the bag to a stationary object, as well as keeping the bag closed with a swaged on brass bead that prevents the opening of the bag when the lock is in place. This bag is perfect for storing anything of value when you absolutely cannot take it with you. I use mine in the car or hotel rooms and can rest easy knowing the things inside will still be there when I get back. The TravelSafe is not large enough for a laptop, but will fit items up to 8" by 13" by a couple inches thick. It is a great accessory for anyone traveling with valuables that need to be secured.
