My project reimagines the everyday school and gym bag through a sustainable, multifunctional design. Designed for students aged 15–25, it transforms seamlessly from a backpack to a duffle, while reducing waste by incorporating recycled textiles and repurposed materials from old bags. The design focuses on durability, comfort, and organisation, supported by targeted research, user feedback, and hands-on experimentation. More than just a bag, this project responds to real user needs and growing demand for eco-conscious products. It aims to prove that sustainability and style can coexist, and that thoughtful design can make everyday routines simpler, smarter, and more responsible.
