More about the Greased OBT Belt

There are no dyes, the straw colour comes from the oak bark liquor that the Devon cowhide was left steeping in (tanning) for a year and a half. This colour will become darker over time - UV light darkens natural undyed leather.

After the tanning process the hides are greased with a mixture of tallow and fish oils which gives the leather the unmistakable leather smell.

The buckles are sand cast at a Walsall foundry, where lorinery has been a speciality since the eighteenth century.

We fasten the buckle to the strap using hand peened solid copper rivets.

Our Greased OBT Belt is 4.5 - 5mm thick and with care (a tub of Hide Food is included) it should last a lifetime

Uniquely Crafted

The leather has a full grain finish which means that every blemish or scar on the cows skin will be present on the finished hide and apparent on the finished product.

The natural colour will darken over time and the feel, initially stiff, will become more and more supple - but never floppy!

Wear this belt every day and watch the patina in the leather, the brass buckle and the copper rivets develop over time. Feel free to take some brass polish to the buckle if you want to go out smart.

No two are the same.

Natural leather needs feeding from time to time (more often in a dry hot environment). Apply a lavish dose of Tanner Bates Hide Food every 6 months to ensure long and supple service. A complimentary tub of Hide Food is supplied with every belt.

Love your Leather

Our leather is ethically and sustainably processed. The tannery uses a mixture of tree barks to transform the animal hides to leather. This is an ancient tradition which yields the familiar leather smell. Natural oils evaporate over time and need replenishing. Your leather benefits from and will look its very best if given an occasional dose of natural waxes and oils. Our Leather care information card is included with every purchase.
