Where have these been all my life?!? If you're a big guy, JUST BUY THEM ALREADY!
5
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.

If you’re losing the fight to the “battle of the bulge”, a pair of men’s support briefs can help. Our 8-inch Belly Buster Support brief gives you maximum compression support and plenty of comfort in a discreet shaping solution. Just step into the brief, zip up the belly band, wear your regular, everyday clothes, and no one will be the wiser. It’s time you had the flat, firm midsection you want.

Maximum Mid-Torso Support

  • Built for men, the Zip 'n Trim disappears under clothing and so do the bulges.
  • Of nylon and spandex, this firm control men's brief provides you with a toned  mid-section, shapely rear and hips,  the waistline you want, and the back support you need.
  • 8‑Inch Compression Band: A 8-inch elastic band provides the ultimate compression and shape.
  • Back & Hernia Support: This brief features a front quarter zipper for easy on and off and a strong non-stretch panel that completely covers the mid-section provides you firm and balanced support.
  • Hidden Fly Opening: A hidden fly opening makes bathroom visits convenient.
  • Made from high quality materials and construction.
  • Made in the U.S.A.

Support Only You See

Support garments are just as private as regular undergarments, and we believe they should be just as invisible. Call us at 1-800-242-4224 if you have any questions about our material, craftsmanship, or how our garments can help you have the body you want. Look great in suits or tee shirts with your men’s compression underwear.

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.
