Pret is proud to support the Cystic Fibrosis Foundation and gives you the chance to help them give back. They have worked with the CF Foundation to create a limited run of the CFF 65 helmet. For every CFF 65 purchase, Pret will donate approximately 20% of the sale back to the CF Foundation. The design of the helmet was inspired by the term "65 Roses", often used by young children with cystic fibrosis to pronounce the name of their disease.
