Familiarity: I returned this product before using it
The product listing describes it as a "wool blend." But the content tag says 97% cotton, 3% elastane. It's also not adjustable (not matter what the tech specs to the left say. Just an elastic at the back. It's a baseball hat. A nice one, but basically just a baseball hat.
