I wouldn't wear one, let alone get one for my daughter. Find a high quality full-coverage helmet that fits well. I have an Arai RXQ and a Vector, they fit me great, both models are "medium oval" shape. I can raise the shield from locked to open with gloved hand. They have a number of vents, too. I wear glasses, prescription lenses (Trivex) in Ray-Ban Aviator frames, black frames so they don't reflect inside the shield. The Aviators are easy to slip into the helmet.
