Gretchen Cordy's kids' vest

In the "Prepared to Survive" DVD, Gretchen shows a orange vest with cargo pockets and D-rings that her children wore when they went camping. Does anyone have an idea of where those can be found?

I'm one of the producers of the Prepared to Survive DVD. Thanks for the postive comments. Gretchen literally made the vest from scratch. Bought a pattern, cut the material etc. Ingenuity at work.
