About Rue Jacob

Ever since the day when the RUE JACOB brand was born in 2000, we’ve been driven by a passion for creating the softest, finest, most luxurious cashmere in the world.


We’re at the heart of the renowned Scottish knitwear and cashmere industry, located in Hawick on the banks of the River Teviot, deep in the Scottish Borders.


We’re obsessed by perfection. We buy only the highest quality raw cashmere and transform it into a sublimely soft yarn, thanks to the soft water that endlessly runs beside our mill. Such is the softness of Scottish water that it’s impossible to replicate this anywhere else in the world. Next, we marry together the best traditional skills with the latest technology and design, creating beautiful cashmere garments that are exquisite to touch and wear. And their inherent quality means each piece can last for decades.


All our cashmere fibres come from the finest under-hair beneath the thick exterior coat of the cashmere goat living on the icy plateaus of Inner Mongolia.


The rarity of the fibre, and the difficult conditions under which it is gathered, are the reasons why cashmere is so precious.

It takes the under hair of at least three goats to create one sweater and twenty-four goats to produce enough for a cashmere coat.


We only accept a small fraction of the harvested raw fibre for processing - fibres that are a minimum of 34 mm in length and a maximum thickness of 16.5 micron. Yarn that is spun from fibre that falls short of these specifications will be weaker and will result in quick pilling with wear, it may also tend to lose its shape.


Only the finest of fibre is selected by Rue Jacob to be made into the world’s most desirable knitwear.
