Helmet Features:

The interior of the helmet is composed of a hypoallergenic padding by Polygiene®, a technology that neutralizes odors by stopping the growth of bacteria and fungi. Sweat has no smell, but it helps create the perfect environment for the smell that bacteria cause when they multiply. Polygiene uses natural silver salt, a very effective antimicrobial agent, to inhibit the growth of odor causing bacteria and fungi. However, Polygiene does not affect the bacterial flora of the skin. And without the smell that bacteria cause, the freshness in the lining is maintained at all times. Guaranteed during the normal life of the product and verified through field tests by the main brands.

The N2C5 communication electronics

Our Advanced NAC-Intercom communication system for 2-meter FM radios, PMR446, LPD443 or FRS/GMRS. Connection is established by an interchangeable, spiral shielded cable (to avoid any interference) and a Mini-XLR connector. Therefore, you can use this helmet with multiple different radios, replace it easily if damaged or simply do not plug it to avoid entanglements if you fly without a radio.
The microphone is very flexible and can rotate 270º so you can either place it on the left of right side. It also incorporates an electret noise cancel microphone with a windstopper foam cover. Furthermore, N2C5 (Before NAC-2000C/AV) allows to adjust the microphone gain - something that we already do at the factory. Nevertheless, it can be modified if the walkie model requires it or if the transmitting signal volume is very low. Also includes volume control in the headset, to costumize even more the sound reception on flight.
Communication is activated by the PTT button (Push-to-Talk), which is placed on the outer part of the shell (You can choose the side where you would like it to be placed). The PTT button is wide and sensitive and has been made with silver contacts and a constant pressure for a flawless performance. The excellent quality of the communication is achieved thanks to the noise suppression obtained by a microphone that has been specifically designed for these purposes. If your walkie comes with a VOX system, then there is no need to press the PTT. Just talk to activate the transmission. (A special cable might be necessary but we strongly disapprove of using it to avoid an accidental activation of the transmission). Lastly, it is possible to choose a medium or high-attenuation ear defender depending on the intensity of the noise generated by the engine (OPII to medium attenuation, OPIII to high attenuation and X5 to extreme attenuation).

Sizes of Helmets

Es importante que antes de comprar tu casco compruebes que la talla que vayas a seleccionar sea la adecuada para ti.
Seleccionar el casco adecuado es importante para tu seguridad, por ello te recomendamos que sigas los siguientes pasos para escoger tu talla de casco antes de realizar el pedido.

Types of Hearing Protection

3M PELTOR OPII (31dB)

Developed for demanding noise-hazard environments and muffles even extremely low frequencies to a maximum degree. The sealing rings are filled with a unique combination of liquid and foam. The result is an optimum seal with low contact pressure, which provides snug comfort even during long-time use. The sealing rings have ventilation channels and are covered with soft, patterned, hygienic foil.

3M PELTOR OPIII (34dB)

Optime III is a super-muff, and has been developed for use in extremely noisy environments. The protection is based on a technology with a double casing that minimises resonance in the holder casing, an acoustic connection between the inner volume and the volume between the casings in its turn provides maximum low-frequency muffling. This results in maximum high-frequency muffling, while at the same time its still easy to understand speech and signals. The sealing rings are broad and filled with soft plastic foam for the best fit and low contact pressure.

3M PELTOR X5 (37db)

For use in extremely high-noise exposure environtments keeping a lightweight with excellent balance and comfort. Unique attenuation as a result of optimum combination of specially-formulated foam featured in the earcups, cushions and the innovative spacer and cup design, and a newly-designed spacer improving attenuation without excess bulk or weight.
Earcups tilt for optimum comfort and efficiency, wire headband offers comfortable pressure, a new special foam.. makes this groundbreaking ear protector a pleasure to wear during prolonged usage.
