I wear a RED (burton's saftey brand). It works great, and it's really light compated to many other's ive tried on as well as alot of RED's line of products from last year. It doesnt affect vision at all because they make the front of most helmets accomidating to goggles. I've never worn my helmet without goggles so I couldn't tell you if it does anything to vision in that case, but i think helmets without goggles look funny enough as it is. Just bring your jacket/neck and face gear/goggles to a local ski shop and try on helmets with everything else on to see what fits best with your stuff.
