Yes, HyperSoft fibres are indeed biodegradable. As part of our commitment to sustainability and environmental responsibility, we've engineered HyperSoft to break down over time when exposed to a natural environment. This means that once a product made from HyperSoft is disposed of properly, it will decompose, leaving minimal impact on the environment. However, this doesn't compromise the durability or lifespan of our underwear during use. You can enjoy all the benefits of our premium quality, comfort, and fit, knowing that your choice is also an environmentally responsible one.
