Keep your water cold for as long as your ride demands. The Hydro Flask bike bottle is designed for everyday casual commuters to bike enthusiasts.

Project constraints were (1) it must read as a bike bottle on the shelf, (2) must fit in most bike cages, and (3) be insulated. Our process was rooted in trial and error. Prototypes were printed, tested, modified, and printed again until we had a product that fit the majority of cages and bikes on the current market. We also hosted focus groups in two different regions of the country (Seattle and Austin) to better understand our two user groups, the casual commuter and the bike enthusiast.
