Around Thanksgiving they announced a new line of carrying bags, initally for students.
They contain a personal safety alarm you can pull in emergencies. They have different styles of backpacks,laptop bags, and also waist packs that I think are good for seniors as well. ($39.99) You can see pictures at the link below, and can order there too. I think they sell them at Toys-R-Us too.
