A Clothing Company That Makes My Heart Flutter

Empire Canvas Works - I'll be ordering myself a vest soon!

We're Empire Canvas Works, and we're not here to replicate the technology-laden garb you see on retail shelves. Our task is to harness the steady function of natural fibers, and blend it with a few modern traits that ensure comfort and durability. We believe that your garments, handwear, and footwear should work the same way, every day, despite age, wear, and exposure to the elements. Our goal is to sell you a great product- once. Your task is to wear your mitten palms smooth on the Hickory of an axe, collect generations of puppy hair on your vest, and listen as the tight fibers of your anorak sing quietly against the brush for miles on end.
