Duffily Bag

Solution Overview & Benefits

The Duffily Bag is a sleeping bag designed to alleviate the problems faced by homeless people sleeping on the streets. It is lightweight, waterproof, heat-retaining, non-flammable, highly reflective, and made of metallic bubble wrap.

History & Development

Emily Duffy developed the Duffily Bag in order to solve some of the problems with existing cloth bags. Emily developed the prototype Homeless Wrap when she was 14 and showcased it at the BT Young Scientist Competition in 2015. The Mendicity Institute reached out and formed a partnership where service users were employed to manufacture the sleeping bags and distributed around the greater Dublin area as well as to refugees in Calais and Dunkirk.
