One of the most difficult things for us about selling motorcycle riding gear online is advising customers on helmet fit. Overall size is a factor but matching the shape of your head to the internal shape of the helmet is just as important. You might have some experience in trying on a few new helmets or have a brand preference, but there are just so many brands and models! And the shapes of different models vary… even within a single brand. All these fit issues are why we created the LidPicker.
