the only trustworth source is an american. And I only know of two companies I have had any dealings with. One is Iron Fist. And the other is Arago out of Florida. Iron fist's shorts are decent. A little limited on their design abilities. But they do promise and deliver. The down side is the design, and semi decent quality. Blank MMA short company number 2 is Arago out of Florida. I bought 50 pairs of their blank mma grappling shorts for a client. I was rather impressed. First they offered embroidery in 6 colors free. Second the owner is an american fighter. I have since ordered several hundred pairs this year from them and have had nothing but good experience. The shorts are actually way better quality than expected. Shipping time was exactly 3 weeks. Sizing was 100 percent accurate. I really liked them. They have a website called fighter magazine. And they all actually fight. So I was impressed by their operation and their clothes.
