NWOT The Normal Brand Mens Seawool Nep Crew Navy. Size M. Never worn. Perfect Condition. Only tried on by my husband who removes tags before he decides to keep items. Directly from the Brand - Seawool is a sustainable fabric that’s built to last using recycled plastic bottles and oyster shells. Seawool is warm yet breathable, and has natural anti microbial properties that keep it from developing a smell. Seawool is static resistant, ridiculously soft, and looks great with just about anything.
