Fit and the exact version
Try the helmet on before committing to a size: check even contact around the head and secure retention with the strap fastened. Shell specifications do not establish whether its internal shape suits you. If you use glasses or an intercom, check their fit with this exact helmet and the relevant fitting instructions.
