MARO 100% Plastic-Free Boxers are made in Portugal with 100% GOTS Certified Organic Cotton. They have a looser fit like traditional boxers but are constructed more like boxer briefs. Most underwear advertised as "plastic-free" really isn't. Other brands use the term "exclusive of trim" so that they can say their underwear is 100% Cotton. This is because their waistbands are made of spandex or elastane, which often comes in direct contact with the skin. We use a completely natural waistband made with 50% Natural Rubber and 50% Organic Cotton. This waistband is covered by Organic Cotton for extra comfort, so it's not visible, but it ensures that our underwear is 100% Plastic-Free.
