Made from a unique yarn blend whose source gives them their distinctive color. Derived from the manufacture of military uniforms, this 100% recycled yarn is a blend of cotton and synthetic fibers. The presence of Kevlar[R] in the recycled material provides added toughness and abrasion resistance. This yarn is highly absorbent and durable enough for heavy-duty cleaning. Tailband helps reduce streaking, snagging and loose strings. Launderable and reusable. Good for heavy cleaning. Made in the USA.
