THERE WAS A TIME WHEN PEOPLE MADE THINGS. A time when production wasn’t just the concept of a factory in the concept of a place you’ve never been, but rather something happening in a real place, where real people that you actually knew put their hands on things. A time when outdoor clothing and gear was built by a core community of people trying to find a way to spend more time outside - not by consultants in a conference room debating whether blue really would be the new blue this year. -Voormi

1949 saw the true start of the red flannel manufacturing with Mae Oppeneer stitching undies in her home and in 1952, the business became known as the Francis Lee Red Flannel Factory. Soon, the business grew into an industry, Underwear was now being stitched on machines at the Cedar Springs Red Flannel Factory. Sadly, the factory suffered some setbacks over the years and in 1994 closed with the headlines predicting "No red flannels in '95". However, local business women kept red flannel production going in Cedar Springs because they believed that red flannels were just too important to fade away. Through the efforts of seventeen seamstresses, family, and friends, there were red flannels not only in '95 but every year since. In 2007, the company was purchased by one of the seamstresses in an effort to keep the red flannel spirit alive. The company will be called the Red Flannel Factory once more. With wholesale and internet tools, Red Flannel Factory, LLC hopes to cover the world in red flannels! -Red Flannel Factory
