What do girls do with their discarded underwear?

Save some old underwear, change it when traveling, then cut it out and throw it in the trash can behind the hotel, out of sight. I just threw away my underwear and didn't feel any psychological problems. But the bra has never been thrown like this, and it always feels strange. Before throwing, I will clean the dead corner of the bathroom with underwear, which is clean and hygienic, and can prevent the satyr from picking it up.

Fabric introduction:

1, pure cotton fabric: pure natural, non-irritating to the skin, hygroscopic and breathable, although it absorbs sweat, it is not easy to dry, and the skin is prone to redness, itching and so on when it is exposed to wet clothes for a long time. So in cold outdoor sports, such as skiing, it is the most horrible invisible killer.

2. Bamboo fiber fabric (fabric containing 95% bamboo fiber): The cross section of bamboo fiber is covered with large and small oval pores, which can instantly absorb and evaporate a lot of water. The natural height of the cross section is hollow, which makes bamboo fiber known as "breathing" fiber by experts in the industry, and its hygroscopicity, moisture release and breathability also rank first among major textile fibers.

3.CoolMax fabric: Coolmax is DuPont's high-tech moisture-absorbing and breathable polyester fiber. CoolMax has strong air permeability and good humidity control performance, which can absorb excess heat and sweat generated by human body from the skin and conduct it to the surface of fabric, thus quickly evaporating.
