I wanted to recommend the company Madlug - it was set up by a youth worker who was appalled to see children in care carrying their possessions in bin bags when they moved home.
This company donates a bag to a child in care for every bag sold. They are providing bags to young people I work with and it makes a huge difference to their dignity.
Madlug sell back packs, laptop bags, gym bags and bum
Bags!
Highly recommend and lovely quality. If you want a 10% discount code - use Wokinghamcares ( don't need to use a capital W). Def worth a look
