Bono's wife Ali Hewson has designed a special range of t-shirts designed to aid relief efforts in Africa.
Bono's wife Ali Hewson has created a T-shirt range with the aim of "alleviating poverty".
Ali - the founder of ethical brand Edun - unveiled the collection, which has been made in collaboration with children from Kenya, at London department store Liberty.
She said: "I first travelled to Africa in 1985 with Bono and it was a journey that affected both of us deeply. We've been back many times since. We both want to show the beauty of the continent.
"Kibera, where the school is situated, is one of the largest slums in Africa and is home to more than 100,000 orphaned children. The people who run the school are very dedicated, and the children so enthusiastic, we felt compelled and inspired by their energy. With these Ts we are able to provide funding to for basic school supplies, hot lunches and healthcare."
The T-shirts have been made to have a dusty and weathered feel to "evoke a trek through the Sahara".
