Maker & Impact
Crazy Boys yarn has been reinforced with Amni Soul Eco®, an environmentally friendly, biodegradable polyamide. Although it isn’t as sustainable as the pure natural fiber, it’s a good compromise because it makes the yarn robust, tear-resistant, and durable. Amni Soul Eco® biodegrades under landfill conditions within five years. That’s ten times faster than conventional synthetics. Only these biodegradable components are released into the environment during normal use or washing.
