A next-generation helmet by Tonfly is specially developed for high-speed flight.

TFX is the first Full Face Helmet made by Tonfly as a result of intense Research and Development. It was developed to have the tightest fit and stability possible, even at very high speeds.

The main reason behind the decision to develop a modular helmet and the flip chin is simply to be able to fit in it. Otherwise, it would not be possible. Once the helmet is on, it is possible to keep just the visor open.

TFX is engineered to have a tight fit that protects from the base of the head and covers all around the neck. Tonfly simply wanted a small, protective helmet made out of the highest quality materials. The flip chin also allows for communicating easily without taking off the helmet, such as for quick debriefs between tunnel sessions.

You only need one hand to open the visor or the chin piece. The visor opens by pushing the hook out and up with your thumb. The chin piece opens by pushing the button down with your index finger as you lift the chin up with your thumb.

The modular lining system of the TFX allows the tightest fit and combines maximum comfort with great stability giving you real protection from the base of the head up. The TFX lining is made with top-quality antiallergic materials. The lining is removable and washable.

Tonfly's TFX is protective for real. The shock-absorbing EPS liner keeps your head safe. The shock-absorbing EPS liner is combined with the double-density foam ears. Both ears can accommodate one audible altimeter on each side and fits the most common audible from LB Altimeters: Solo, Optima, Quattro, and Protrack.

The TFX features a double ventilation system to keep your mind fresh even after intensive use. There are 2-way in/out airflow vents at the top and back of the helmet as well as an in-air flow vent for internal visor ventilation.

The TFX has been inspected and tested for the following:

  • Construction
  • Shock absorption capacity
  • Determination of field vision
  • Penetration test
  • Retention system performance
  • -20 degrees Celsius cold conditioning
  • 50 degrees Celsius hot conditioning

  • Complies to the newly developed Skydiving Helmet Standard XP S 72-600

So wide and so clear describes the TFX visor with a super-wide visual field as well antifog and anti-scratch system. The visor is 2.3mm thick polycarbonate that guarantees a wide visual field without image distortion. The TFX visor is available in clear, brown, or smoke.

The visor has been rated under EN166 for Personal Eye Protection and tested for the:

  • Field of vision

The secondary lining is based more on the shape of your face and is available in 3 different thicknesses: 5mm, 10mm, and 15mm. This allows three different fits for every available size, giving the TFX 36 different available size combinations between shell size, mainlining, and secondary lining.

You can submit your own measurements following the measuring guide below. See the image below for a demonstration of the 3 measurements, plus the additional description below. Contact us for additional help with how the measurements are taken.

TFX Measurement Demo

  • Head Circumference: Measure the circumference of the head at the forehead height, being careful that the tape is horizontal and has the right tension (not too loose, not too tight)
  • Face Circumference: Extend the tape measure around the face, being careful to pass it on top of the chin, above the ears up to the top back of the head.
  • Face Width: Measure the face width by positioning 2 rulers (or similar objects) at the base of the ears and make sure they are held vertically and parallel between them. Extend the tape horizontally and measure the distance between the 2 points.
  • Upload a photo of the Face Width measurement being taken.
