This exploration into product design was developed in response to the pain points of having to carry numerous personal items throughout a public gym, a context where sanitation concerns are high and pocket storage is low or non-existent. Our product, printed out of flexible TPU and silicone, leverages a sleek, attractive design that allows users to access essential items quickly while minimizing contact of these items with dirty surfaces. Key features include a multi-card holder, carabiner clip, mag-safe phone mount, and magnet mount that enables users to attach their Hydro Koozie to any metal surface, thereby eliminating the need for repeated and uncomfortable positioning.
