We do turn our heads to face the direction were going too... Maybe not all the way but defentily close. I don't think it's a huge difference. I've seen snowboarders wear I/Os and such and have no problems, yet my new anons are labeled as specifically "snowboarding goggles" under uses on the label. Maybe you're right. Who would like to have a multipage debate with me about how the laws of physics affect goggles in blizzard conditions in 12 degree (f) weather at 922ft elevation, facing north on a mountain in northern Vermont during a low pressure system.
