For reference I take a size US 33-34 waist in jeans. I'm 6'1" about 185lbs. I ordered the XXL in Black/Red. These are actually orange. There is a meshing over the front crotch area that makes them appear darker but on the inside they are bright orange not red as described. I guess if you are Cincinnati Bengal or a Baltimore Oriole fan you'll like them a lot. They are most definitely see through. Its basically pantyhose material. Given that, there's a lot of stretch to them, (I could have gone with the XL and been just fine). They are comfortable and have a decent pouch but there is not a whole lot of support. It does feel like you have almost nothing on. I'm not crazy about the color but I decided to keep them. Would I buy them again? Probably, but not till the summer time.These run very small. AND, they need to change the color description to black and ORANGE, not red!!!!Very pleased with the purchase. Exactly as described.Go two size largerI will buy more of theseVery nice!I ordered these because of the color was described as black and red. They arrived but the colors are black and rust or a brownish / orange color. I was very disappointed and will return them.Love them. If u have to wear underwear this is the choice.
