Helmet goggles are designed to work in conjunction with a protective helmet. They can be used for motorcycles, snowmobiles, scooters, as well as for skiing, snowboarding, and other extreme sports. They are almost exactly like regular goggles aside for two aspects, the strap has to be longer than normal and often the frame has to be a little smaller to fit inside the helmet.
Helmet goggles have all the regular features of those worn without a helmet, such as anti-fog coating, protection from rain, ice and snow, and of course the bright and damaging rays of the sun. Although those rays are good, long exposure to them can cause a number of problems that aloe would never be able to take care of.
Helmet goggles can be found anywhere goggles are sold. Many regular designs actually work very well inside of a helmet without any changes to the frame. Smaller frames work well with or without a helmet, but the helmet provides much more protection.
