The name says it all: GRS is the Global Recycling Standard, so you can create projects for yourself and help protect the environment while doing it. And Amicor provides long-lasting protection against odor, allergens, and bacteria (up to 100 washes), keeping garments feeling fresher for longer. Tried and tested for 30 years, additives release over time, making the yarn properties resistant to washing or wearing away. It’s certified safe for babies and kids, as well as bedding, hats, gloves, pets, and beyond!
