Hi, I used the red helmet for probably 5 years. The sticker on the inside says M/L and I am guessing that that is the size. It has front and rear paddings but the front left and right I think have fallen off- should be able to replace that for super cheap. custom The Bell helmet, the white one, I barely used and is perhaps an XL, but really both helmets were fine for me and I think I have a large head. They have adjustable knobs on the end to adjust to various sizes. I also include a bike repair kit with tools and tire changing goods. Act now, and I will add the two sets of glasses for free!
