I researched a helmet for months. Finally took the lung and picked this helmet up based on STG helmet review. So far this helmet is amazing, the fit is near perfect. The weight is very light, love the color. The air flow in this helmet is also great. As of noise I would say it may be normal maybe a little lower. I don’t wear plugs though ether. The size of the helmet is great as it doesn’t hit my suit like the other helmet. I highly recommend this helmet to anyone.
