No clue, but you might want to look into Bohn armour, it's a system you wear under regular clothing,

I've been using the Bohn system for several years now. They have a full line of armour systems, including back protection, replacement armour for regular gear, etc..... You also might want to consider it for yourself.
Also show your daughter Britney "Queen B" Morrow's website, and the organization she started when she learned the hard way about gear. I personally know her, and she's truly an amazing person.
