S.U.I is a sub brand for a young persons charity organisation called CAYSH, the charity wanted to update the look and feel of S.U.I.
 
S.U.I is specifically aimed at homeless teenagers—CAYSH wanted the sub brand to be youthful and to concentrate on the positive aspects of their work. This was achieved with the use of vibrant colours and the double stripe on the branding; which symbolises sport, youth and energy.
