You know, we wouldn't proclaim "America’s Finest Ranchwear" if we didn't believe it in our heart and soul. The pride we carry of being one of the last U.S. designers and manufacturers of genuine, salt of the earth ranchwear is a feeling that's hard to describe. -Schaefer

Each Schaefer Outfitter garment is proudly American made in our family owned and operated factory, which means we design, engineer, cut, sew and inspect each and every garment featured in the product line. In fact, Schaefer is one of the last full line apparel manufacturers left in this great nation of ours. We not only produce American made garments, but firmly stand behind purchasing American made raw materials right down to thread, snaps and labels. The result of your support is not only heart felt to our small company and its employees, but to the hundreds of folks from coast to coast in the textile industry who provide the finest raw materials possible. Thank you for supporting American made products. -Schaefer
