This helmet is designed for extreme pumpers.
With a diameter of 52 mm (≈ 2.05″), this helmet plays in a different league.
Here, it’s not the cylinder diameter that matters — your grid is the decisive factor.
This model has been optimized specifically for grid performance. Whether your cylinder is 3″ or 4″ is less important in this case.
⚠️ Important sizing information:
The inner diameter of the helmet is 52 mm (≈ 2.05″).
The cylinder used must be at least 2.5″ (≈ 63.5 mm) or larger.
In addition, the penis must completely fill a 2.5″ cylinder when pumped.
If this is not the case, this helmet is not the correct size.
Developed for those who want to achieve maximum results and accept no compromises.
