I prefer subtlety to more in your face attempts to safe guard my valuables when traveling but for some who have come to reply upon the false security hotel safes this might be a necessary product. No doubt that this will deter but the more determined thief. This tough bag is made with high-tensile, stainless-steel wire which is laminated between durable nylon fabric to form a rugged pouch. The bag cinches at the top with a draw wire which you secure to the heaviest object in the room with the included padlock. About $40.00US from REI. Via uncrate.
