The Mechanics Hat
Based on the original WW2 USN Wool Hat.
The style is commonly referred as "watch cap" as it was used by soldiers to protect them from wind and weather when they were on deck for their watch.
This version has a double fold to adjust the rim to wear it either above the ears or to cover them when needed.
It is hand finished, due to the sophisticated knitting technique it will mould to your head just after a few wears.
