Taking the brand’s textbook ‘bubble knit’, this winter warmer from S.N.S. Herning sees the addition of full zip to the classic original sweater. These guys know a thing or two about knits, having manufactured them for over a century.

Made using 100% virgin wool and polished off with a ribbed collar, cuffs and hems, a RiRi zipper rounds things out. For true Grandpa at Christmas vibes, the Fisherman Full Zip features a drop shoulder and fuller fit. Chose from Lacquer Green, Black Void or Navy Blue, and don’t forget to be extra grumpy like gramps.

Available for $305 at BlackBlue.
