What do you call this type of head covering?

Knit cap

If you don’t want to see a Zeldar poll, then perhaps this one will work better for your curiosity.

Before dropping the subject I’ll mention an old thread on a similar issue/topic:

Thank you for restraining yourself, just this once. Really.

A toque/tuque.

Not according to the preeminent authorities.

Toque.

Beanie

If I was in design class or writing/drawing a plate, a toque.

Anywhere else, depending on who I’m talking to, and how much regional accent I’m scrubbing at the time, either a knit cap, stocking cap, or toboggan.

I’ve always called it a stocking cap.

(Grew up near St. Louis in the 70s-80s, FWIW.)

Dammit, Grandmother Plant knitted them, and she knew what she was about, and called then toboggans.
One must not go against the lessons of childhood, save for those damn balls she put on top.

That one in the OP is a watch cap. The best ones are Navy surplus. They’re worn by sailors who are standing ship’s watch. They’re simple & practical. Originally, they were wool, which keeps its insulating properties even if it gets wet. Toques & Beanies and such will be different colors, with decorations. Watch caps are strictly functional.

I must admit, “watch cap” is much more macho than “toboggan”.

Yep, that’s definitely a beanie!

Beanie.

Knit hat

Others call it a watch cap, because it’s what you have to wear when you’re on watch on deck, because it’s damned cold.

I don’t know anyone who calls it a watchcap; that’s just silly.

Agreed.

Also, these are both handy Scrabble words.

Toboggan or boggan. My dear Canadian born friend argues with me though that it is a toque. I have heard watchcap, and knitted hat.

Yeah, it’s a touque in Canada, although we can’t seem to agree on the spelling!

I have never heard it called “knitted”, only “knit”.
