Arm and hand warmers made of exceptionally fine merino fibers measuring an average of 16? (microns) which is equivalent to that of cashmere. Soft and luxurious, they cover about 3/4 of the forearms (13" long) and most of the fingers, leaving only the tips free for practicality. 100% New Zealand Merino Wool, made in Japan. Made in Japan in a 3rd generation sock factory. Nishigushi Kutsushita (Knitwin Co.) started in 1950, shortly after the war, with one hand-knitting machine. They now have 130 machines in operation and work with a team of craftsmen that ranges from 50 years of experience to younger employees who they hope will lead the company into its future.
