Dr. David is a super underwear with soybean protein fiber as the main fabric, which is breathable, dry, bactericidal and bacteriostatic, activates cells and opens up microcirculation. Men's underwear has a good preventive and therapeutic effect on male prostatitis, such as scrotum dampness, frequent micturition, urgent micturition, bifurcated urine, urinary incontinence, drops of urine's disease, and urinary incontinence.

Nowadays, underwear is no longer a fig leaf, but a product of human preventive health care. Dr. David's black technology comes from the far-infrared light wave of life light wave. Using floodlight technology, that is, far-infrared light wave interception and transfer implantation technology, the most beneficial far-infrared light wave in 4- 16 micron band is intercepted from sunlight and implanted into underwear products.

As we all know, far infrared light wave is called the life light wave of human body, and it is the most penetrating light of all sunlight to skin and subcutaneous tissue. Many hospitals use far-infrared instruments for adjuvant treatment of some diseases.

Every fiber in Dr. David's underwear is implanted with far-infrared light waves, which are the most common frequencies with the human body. The effect will not be weakened by washing, as long as the underwear will never disappear in energy. Even if you burn your underwear to ashes, there is energy in the ashes.

After nearly four years of polishing, Dr. David has optimized and upgraded the fabric and packaging. Let a "seed" of that year take root and sprout, and gradually take root and sprout. This innovative new technology and product, with its innate temperament, will not only become a striking "black technology", but also set off a storm of manufacturing transformation and upgrading.
