Cone type only cover the first half of the above, they are very popular on the streets of Vietnam. This type of hat has the lowest protective because it only covers the first half on our side. Other areas such as brine, the face, ears and chin can severely damage accident. However this kind of hat is very popular by the lightweight, airy and compact size, convenient to carry. Caps first half only appropriate to go in slow speed city driving. Not appropriate to go away or driving too fast. This hat also has the advantage that can be used with a wired headset, a Bluetooth headset because the ear of the team not concealed. 

2. Cone 3/4 head (Open-Face)

Cone 3/4 means that it protects the 3/4 of our head, including the top, then brine and 2 ears of the team. With greater coverage cone 1/2 so of course it will protect us better.

The addition of the chin protection is important because according to the study, 35% of motorcycle accidents make the driver's chin badly hurt. Arguably this hat hot and tunnel, but the majority of the cone Full-Face (FF) are currently designing a good circulation system should no longer does both. Currently, in order to meet the needs of Leaders, brothers touring motorcycles , the manufacturer MBH also made ​​many kinds of hats FF good quality while maintaining high aesthetic, light weight (about 1 kg), but not too big and bulky. Ahead hats FF always have a big glass used for shielding (English called Visor). This glass is for sun or UV protection, depending on type. Some hats favored equipped with a second small glass Visor cone located in front of the team, can be pulled down easily to enhance the resiliency of the cone.

A hat FF after an accident, you can see the face and chin get beat up a lot.

This type of hat is essential for those who ride the large because it helps keep the driver from wind snapping in the face causing fatigue, sleepiness and accident prone. When no wind in the face, the driver with the same peace of minds that ... run faster. Normally, if you're not a hat FF that runs at high speed about 100km / h when the "nose tears huts, Colombia", while if the FF team, you will see very normal, can be run with speeds above 100km / h and still feels very stable (not talking about cars that you are running). Similar to cone 3/4, FF hat drawback is difficult to use with the headphones unless you use the headphones designed for MBH.
