Need some helmet product info from ya'll

Hi,
I'm an MICU rn that's just recently transitioned to the admin side of healthcare-value analysis. Our neuro icu is using skateboard helmets for post-op craniotomy patients. I'm wondering if anyone can tell me exactly the specific name of one or two products that I can have the staff evaluate. I've researched molding helmets, but that's not what we need. Any advice as to what you're using in your facility would be greatly appreciated. Thanks and have a great day!
