Apparently, the “Vintage Wool” these Sunspel Long Sleeve Jumpers are made out of is an Italian-spun merino fabric that the company originally developed / used to make underwear. So if it’s good enough for your crotch, it’s got to be good enough for the rest of you, right? And the fabric is machine washable, like any crotch-touching fabric should be. Get ’em at Norse Store.
