No matter what you’re doing – hiking, shopping, going to school or work – you’ll probably need a bag to carry your stuff, and you’ll need to give a thought to your personal safety. iSafe Bags has just announced a waist pack with a personal security alarm built in. They say the iSafe Waist Pack “is the first and only waist pack with a hidden, built-in mobile personal security system to protect the wearer and provide security in threatening situations.” This water-resistant bag is made of Poly 600D fabric. It measures 11″ X 6.5″ X 5.5″ and weighs about a pound with the batteries installed. To sound the alarm, simply release and pull up on the flap you can see in the pictures; lights on the front pocket will also begin blinking when the alarm sounds. The Waist Pack is available from iSafe in black or blue/gray; it’s $39.99. If a waist pack isn’t your style, iSafe also sells school backpacks and laptop backpacks and messenger bags with built-in alarms.
