The correct and safe way is to bring an outer helmet and snow goggles. The design is for snow lovers to wear the snow goggles outside, so that they will be stronger. Foreign ski resorts allow coaches (instructors who train athletes, not public coaches, instructors, trainers) to wear helmets in ski resorts. At the same time, some foreigners express their confidence in their skills and fear of death when skiing in wild snow. Spiritual, will not wear a helmet to ski (very few, and some are for commercials). At this time, in order to keep warm and fix the snow goggles, these real big pros will choose to wear a hat. Domestic snow friends have everything to learn and want to wear a hat. However, domestic ski resorts require helmets, so you have to wear helmets and hats at the same time (which can also keep warm). At this time, the snow goggles will be more comfortable to wear between the helmet and the snow goggles, but it is still very unsafe. Single and double board athletes will never wear snow goggles in their helmets. The reason is that it is not safe.
