The name Saint James has been closely tied to the French wool industry from around 1850.
At first only as the name of a tiny Normandy coast town spinning and dyeing locally produced wool.
But from 1889 on also as the company Saint James, producing among other things the now iconic Fisherman's sweater (little known fact is that in the navy, traditionally a solid blue sweater was to be worn by officers only, while the striped version was for sailors).

I recently got given this knitted hat which will not only keep my head warm this winter, but also dry, as the knit is so thick and dense that it has a water repellent function!
When I was younger I always wondered how my father could wear his Saint James sweaters as the wool was so incredibly rough and prickly. It seems to have simply been a matter of "manning up" though...
(L) I've been wearing it watch-cap style, pulled tight over my head with a high fold up, or nonchalantly pushed all the way to the back of my head.
(R) 100% wool and still 100% made in France. The "traite anti-mites definitif" loosely translates to "definitive anti-bug treatment" meaning that you won't have to worry about it being eaten while it's stuffed away in a closet during the warmer months of the year.
