Should I Get a Full-Face Helmet for Mountain Biking?
Full-face bike helmets tend to be heavier, hotter, and bulkier than open-face helmets. For this reason, you should only wear a full-face helmet if you really have to. Otherwise, you will be uncomfortable for no reason.
The majority of cyclists who buy full-face helmets like to ride a lot of downhill trails at high speeds. If you are in the mountains or back-country while riding your mountain bike, you will probably want to buy a full-face helmet.
Even so, you don’t have to do hard-core mountain biking to enjoy a full face mask. If you are simply nervous about getting a bad facial injury, you will feel safe and secure in a full-face helmet.
Furthermore, these helmets protect your mouth and teeth. Those with dental problems should invest in these products as well.
Overall, it’s up to you whether you want a full-face helmet or not. These helmets will provide extra protection for your brain, face, and teeth. However, they will be hotter, less comfortable, and heavier than open-face helmets.

These helmets will also have visors for the sun and bugs and protect your eyes from tree branches.
Mountain bike helmets are also less aerodynamic than others. The focus of these helmets is not to help you go faster but to help protect your head on brutal trails.
To conclude, mountain bike helmets are different. They are built sturdier, thicker, and more durable than others due to the demand of mountain biking environments.
Can I Use a Mountain Bike Helmet for Road Biking?
If you have a mountain bike helmet but want to do some road biking, you may be wondering if you can use the helmet on the road.
You can use a mountain bike helmet for road biking. However, it will not be the best choice. While the mountain helmet will keep you perfectly safe, it will be bulkier, heavier, and less comfortable than a road helmet.
