Inside our wax factory: 6 months with British Millerain

British Millerain has been weaving waxed cotton since 1880. Their mill sits in a brick building outside Preston, in the north of England, and the fabric it makes has been on the back of every working fisherman, rancher, and surveyor in the British Isles for the better part of a century.

We started sourcing their 10oz waxed canvas for our Ridgeline jacket in 2008. For the last six months, we lived at the mill two days a month — watching, asking questions, arguing about thread count — to understand exactly what we were buying.

Cotton, then wax

The canvas starts as plain-weave cotton, woven tight enough to hold a wax infusion. Then it goes through a wax bath — historically a paraffin-and beeswax blend, now a refined petroleum-and-wax formula that's a closely guarded recipe.

The wax is what gives the fabric its water resistance and its patina. A new jacket is slightly stiff and glossy. A 10-year-old jacket is soft, broken-in, and visibly yours.

Why we don't use synthetic alternatives

Modern technical shells use PU membranes to stay waterproof. They work — better than wax, in the lab. They also fail in seven to ten years and don't recycle. Waxed cotton can be re-waxed in your kitchen with a $12 tin of British Millerain dressing.

That's the argument. We make things that get better with age, that can be repaired at home, that don't have to be replaced when the warranty runs out.
