What is bad about elastane?

Elastane, also known as spandex or Lycra, has several downsides. It is not biodegradable, contributing to environmental pollution as it can take hundreds of years to decompose in landfills. Additionally, its production involves chemicals that can be harmful to both workers and the environment. Furthermore, garments made from elastane can lead to issues such as reduced breathability and discomfort in hot weather due to their tight fit and synthetic nature.
