For some, their water temperature isn't of a concern. However, most of us would prefer a nice cold drink on a hot day if presented with the option. It's for this reason that Profile Design expanded upon its already successful Aerodrink, by now providing an insulated version. With it, you're able to store your hydration between your aero extensions, all while maintaining a consistent temperature in your bottle. So, you'll be able to comfortably rehydrate without deviating from your sweet spot. Even better, the bottle's aerodynamic shape means that you're able to achieve the aforementioned without paying a heavy aerodynamic penalty. Additionally, the Aerodrink Insulated only adds around 39 grams to the standard Aerodrink, making the comfort to weight ratio differential almost negligible. The Profile Design Aerodrink Insulated features a 22oz capacity, and it weighs in around 210 grams. Please note that this bottle does not include the required mounting bracket. To mount the bottle to your aerobars, Profile recommends its Universal Aerodrink Bracket.
