15 year-old Emily Duffy says she came up with the idea after living rough for a day on Dublin's streets, experiencing life as the homeless do to raise money for charity.
Duffy's invention, dubbed "Duffily Bags," have a highly reflective, fire retardant and waterproof shell. Velcro straps replace the usual zippers, allowing the user to get in and out more easily.
The bags are currently being produced by former homeless people now earning $10 an hour at the Mendicity Institution - a homeless service center in Dublin.
