Herdwyck No.10 is a pure wool, its colour and texture derived from the distinctive Herdwick fleece. It is spun, woven and finished entirely in the British Isles. The fleece originates in the English Lake District, Cumbria. The yarn is spun in Donegal, the spinning process is slowed down giving the yarn greater strength. The cloth is woven in Wales, extra picks added into the loom create an unusually dense weave. The cloth is bonded with natural rubber to a cotton lining in Lancashire. The result is a unique, naturally robust and waterproof Herdwick woollen tweed; Herdwyck No. 10.

All CHERCHBI leathers are developed for us with the help of Joseph Clayton of Chesterfield, Derbyshire, who have been tanning leather since 1840. Our leathers originate from Northern Irish cow hide and are pit-tanned using vegetable tannins. This is an ancient process, essentially unchanged for thousands of years. Our bag leather is called CHERCHBI British Saddle. We use the original surface of the hide, or top-grain and retain any individual marks and creases. These little inconsistencies differentiate each hide and make each leather item unique. This is cut at 3mm, unusually thick for bags, and left unbacked so every aspect of the leather is visible.

Our brass metal ware is cast in England where possible. We use Swiss-made Riri zips, widely considered to be the finest quality zip available, as unfortunately no British zip makers exist. Our cotton lining is sourced from a mill in Manchester.

Our main design principle is simple functionality. The bags are easy to use, aesthetically correct and the qualities inherent in our raw materials are visible. Our modern designs are inspired by utilitarian classics and the way such bags are worn and used. Design details are pared down to their essence.

All bags are made entirely in Britain to our robust, traditional quality standard utilising traditional leatherwork and saddlery techniques. The combination of natural materials - waterproof Herdwyck No. 10 tweed, British saddle leather, brass hardware and 100% cotton lining - all age together harmoniously with use.
