Weight:650g+/-50g  EN966 standard High noice cancel system

Characteristic:
Since the back has paramotor frame,the helmet adopt a design that the helmet shell back section sub-circular,so there is no Activity obstacle and At the same time does not affect the use of the overhead umbrella.Application of standard communication system,very good noise cancel system,could let you fly better.A Larger field of view.According to your request,could add different Coated polycarbonate glass visor.Normal we have transparent,mirror, colourful mirror

Material: Outside Kevlar fiber and glass fiber composite materials.By 3 layers of superfine glass steel and then add a layer of Kevlar or carbon fiber composite structure.(Carbon fiber material could be ordered)
The middle layer:Made up of famous EPS material,have good absorption of crash energy
The inner layer:Comfortable, soft and can be parted and washable

Headset:
Over 5 miles Effective Clear pronunciation Call distance.
3.7V, 2200mAh lithium ion battery powered, providing more than 100h working time. There is no need to replace batteries for repeated charging.
Two working modes are selected, and the state of noise reduction and normal state are easily switched.
Functional characteristics:
1, the built-in high precision ANC inverse noise reduction circuit can effectively isolate 85% background noise.
2. The drive unit with a diameter of 40mm is used for noise reduction. The diaphragm is made of high-end material, which fully reflects the clarity and high-quality sound quality of the sound.
3, 3.7V, 2200mAh lithium ion battery power supply, providing more than 100h working time. There is no need to replace batteries for repeated charging.
4, two working modes are selected, and the state of noise reduction and normal state are easily switched.
5. high-grade silicone ear muff, soft and comfortable, not oppressed, long time weary.
