The Watch Cap Type II is an updated on Knickerbockers original silhouette. They were able to produce a denser yarn, which provides greater softness and comfort once worn in. They also opted in for a five to three gauge knit as you can see for yourself at the top of the crown. A tip to our fellow servicemen who commonly wore a similar cap during WWII. They also love the fact that these are spun on the same industrial knitting machines as that of the army.
