Where have these been all my life?!? If you're a big guy, JUST BUY THEM ALREADY!

I'm a bigger guy who is making some life changes and going through some weight loss. Weight loss = good. Extra skin and fat that won't go away without surgery? BAD. I've always been a bit self-conscious about my weight and appearance. I bought these for my midsection to go with a compression top to flatten my man boobs. While I was a bit worried they wouldn't fit me, would be difficult to get on, or wouldn't be comfortable, I was pleasantly surprised to be wrong on all counts. As a bigger guy, I currently have a waist size somewhere between 54-56. I bought a 4x, as the size chart recommended. It fit PERFECTLY. That said, this IS a compression garment so it's intended to be pretty snug, but once I zipped in I was amazed at how firm yet comfortable it really was. The extra support actually helped my back quite a bit as well.

To hell with all this about looks and belly fat; the real use is to relieve back and hip pain, and it does a great job.
