The HydroXtreme range includes several overlapping sizes, which gives you more flexibility when your measurements fall between two models. The best choice is based on your current erect length and girth, not the size you hope to reach.
If you are comfortably within one model’s range, that is usually the simplest place to start. If you are close to the upper end of a size range, compare the next model as well and pay attention to chamber width, length and overall fit.
The HydroXtreme 7 and HydroXtreme 7 Wide Boy both cover the 5–7 inch length range, but the Wide Boy provides additional girth capacity. For users who need more length rather than more width, the HydroXtreme 8, 9 and 11 provide progressively larger chambers.
Before choosing a model, check our Bathmate Size Guide and compare your measurements with the available ranges. A properly fitted pump is more useful than simply selecting the biggest chamber.
Measure your current erect length and girth before choosing a model. Compare those measurements with the available HydroXtreme ranges and select a chamber that provides an appropriate fit rather than choosing based on the size you hope to reach.
Overlapping size ranges are normal in the HydroXtreme lineup. If you fit two models, compare both chamber length and width. In many cases the smaller suitable model provides a closer fit, while the larger model offers additional room.
The HydroXtreme 7 Wide Boy is intended for users who fit the general 5–7 inch length range but require additional girth capacity. It is not simply a larger version of the HydroXtreme 7; its main advantage is the wider chamber.
Usually, fit should be based on your current measurements. An unnecessarily large chamber may not be the best match simply because it offers more space. Compare your measurements with the size chart before deciding.
The main difference is chamber capacity. HydroXtreme 8 is designed for the next size range above the standard 7 models, HydroXtreme 9 provides more room again, and HydroXtreme 11 is intended for users who genuinely need the largest chamber in the range.
Yes. Length alone does not always determine the best fit. Girth becomes especially important when deciding between a standard model and a wider option such as the HydroXtreme 7 Wide Boy.
