Is the AllMatters period underwear vegan?

It isn’t vegan since we use merino wool in the inner layer. Instead of choosing a vegan synthetic material, we chose merino wool since it’s a bio-based material that naturally provides breathability and comfort. It’s also naturally anti-bacterial and anti-odour. We use mulesing-free merino wool from a German supplier that meets OEKO-TEX and GOTS standards.
