Our History

Founded in 1911 by the Rosenburg Brothers, Reliable Knitting Works is a proud, family‑owned company with over 115 years of craftsmanship, innovation, and trust at its core. Today, Muk Luks® continues that legacy under the leadership of Owner and CEO Mark Blutstein, who has been with the company since 1986 and was mentored by his father, Morty Blutstein, and uncle, Jerry Polacheck. Our success is built on the dedication of thousands of employees who share a commitment to quality, customer focus, and evolving fashion trends.
