Where can I buy this type of fabric material?

Question by cantstophop: Where can I buy this type of fabric material?
Hello,
I’m in the Los Angeles area. I was wondering where I could buy some heavy duty nylon material to create a vest like this:

Is have a sewing machine and am going to sew the vest myself. Thanks.
I forgot to mention I don’t need pouches for weights on my version of the vest.

Looks like cordura or similar nylon; I’d go with 100-300D… and I’d put something like Power Dry underneath it as a liner to help prevent hyperthermia.

Head down to the fabric district or order from one of these specialist companies:
