An all season knit cap made of 100% cotton. No pilling or discomfort, which is common in most acrylic or wool based caps. Knickerbocker watch caps are made using the same industrial knitting machines as that of the US Army at Artex Mills - one of the last great knitting mills in the USA.

These beanies start off tight, give them a day to stretch out to the shape of your head and they'll fit perfectly and break in very nicely like any well-made garment.
