While color can be largely a manner of personal style and preference, too, it is a critical consideration for some activities. A black watch cap seems to be a fashion statement made throughout the country by everyone from Millennials to senior citizens. But if you are going to use your watch cap for hunting purposes, black is probably not the color for you. If deer hunting, many states require hunter orange headwear, so a blaze orange cap is going to be your best bet. Likewise, for deer or waterfowl hunting—activities where hiding is critical—a camouflage watch cap will keep your head warm while keeping deer, ducks and geese from spotting you before the shot.
