how health,safety and environment awareness can promote sustainable development?
Full face is by far the safest, or modular if the quality is good. Go for fiberglass or similar material as it absorbs energy much better than the 'bouncy' plastics. Best brand in my opinion (assuming the fit is good): Shoei. 2nd place Schuberth (good luck finding one, especially one that fits though)
Just exactly what are THE Nuclear Alarms you are talking about. You really don't have a clue what you're talking about do you?
full face shield with flip down clear shield to keep the bugs out as your zooming along there are lots of brands out there just get the right size for your head and rembember that helmets deteriorate over time try not to scratch it too much most helmets nly have a one year warranty on them, and if you were to get in an accident and live to tell about it it would probably be a good idea to get another helmet. The warranties would be void after one impact the helmet might look ok but better safe than sorry.
all brands aside get what has dot and snell safty ratings then get what feels best on your head different helmets fit differently
Full face. Get one that fits and has a DOT sticker, and a Snell rating. My helmet is an Arai. It was cheap because it has stickers that read Suzuki on it, and it was being sold at a Yamaha dealer. LOL.
