Directly from the mfgr who makes it for Mossy Oak Licensees. I had to get permission from MO to buy from their source but the majority of the fabric was bought for the Big D Hunting Retriever Club in Dallas to make holding blinds for their Hunt Tests and Field Trials.

Since it wasn't being re-sold and I bought in a large enough qty, Mossy Oak gave permission.

You can buy almost the same thickness of material from Macks PW. http://www.mackspw.com/Item--i-AVE3275S
