Ergowear specializes in 'ergonomic' underwear and swimwear. The Ergowear X3D Underwear collection includes thongs, bikinis, mini boxers, briefs, and mid cuts. The Ergowear signature three-dimensional pouch is common on all of them. The nose-shaped pouch has a lifting effect with a slight push up for added comfort and movement. All of the X3D products are made of Microfiber, giving you high elasticity and breath-ability. The bulge has medium depth and vertical seam with concealed waistbands, except for mid cuts. Be sure to look at the X3D Suave styles which are made of Ergowear's newest material, the suave microfiber. You have to feel it against your skin to believe it. You can Buy Erogowear X3D here.
