I only used my Respro Foggy last winter and now the velcro isn't sticking to the inside of the helmet and I need to use it for the mornings as its been in the 20's. Is there something I can do to make the velcro start sticking to the inside of the helmet or am I going to need to purchase a new one as this is something that happens and is normal? I did not use it that much but it does help when I need it.

Thanks in advance.
