About Polyester Spandex

Underwear For Men’s Polyester Spandex blend is 90% Polyester and 10% Spandex. Polyester is a synthetic material that is loved for being machine washable, wrinkle-resistant and affordable. Spandex is used to add stretch for added comfort and support and maintain shape.

Benefits of Polyester-Spandex Underwear For Men

  • Polyester fabrics and fibers are extremely strong.
  • Polyester is very durable: resistant to most chemicals, stretching and shrinking, wrinkle resistant, mildew and abrasion resistant.
  • Polyester is hydrophobic (water repellent) and quick drying.
  • Spandex is lightweight, retains original shape, no static or pilling.

Carmelo B says, “Best underwear. My boys have never felt so comfortable. I gave up running because of the discomfort. But now I'm running again and I feel great. I'm a fan for life. Thanks, UFM!”


Keith C says, “Awesome underwear. I walk an average of 8 miles a day at work and go up and down countless stairs. I'm 50 years old and needed some extra support. I had started wearing a jock strap. Not the most comfortable thing to wear for 12 hours. Began surfing the net looking for a solution and found UFM underwear. I feel like I get more support from this underwear than the jock strap. Breathable, comfortable, adjustable and AWESOME. I plan on buying two pairs every payday until I get a full set.”

About Viscose Bamboo-Spandex

Underwear For Men’s Viscose Bamboo Spandex blend is 95% Viscose and 5% Spandex. Viscose, more commonly known as Rayon in the US, is a man-made fiber created from cellulose chemically extracted from Bamboo. Viscose Made from Bamboo is loved for being structurally similar to cotton, but unlike cotton, it has moisture wicking properties. Spandex is used to add stretch for added comfort and support and maintain shape.

Benefits of Viscose Bamboo Spandex Underwear For Men

  • Viscose Bamboo fabrics and fibers are ultras soft for a cottony-like feel.
  • Viscose Bamboo is very breathable, easy to care for, lightweight and fade resistant.
  • Viscose Bamboo is naturally hypoallergenic and quick drying.
  • Spandex is lightweight, retains original shape, no static or pilling.

Sean H says, “Room, comfort, and air. Love these Bamboo 6" briefs, they breath and move with room to avoid the tight spots and the customer service from UFM is top notch and easy to get a hold of. I'm a repeat, repeat, and now repeat customer who has a whole side drawer of old-style underwear not being used and a nearly always empty UFM side of the drawer (my favorite pairs in the wash or dry). Thanks, UFM, for freeing the fellas.”

Daniel R says, “Amazing feeling and comfort. They feel like they are not even on and the support everything just right. good for sweating a lot and overall exercise.”
