What head size is the "One Size" Minus33 Merino Wool Ridge Cuff Beanie

It means it's for "average" sized domes. The respondents claiming it will comfortably fit all head sizes are likely the same 5'10 guys claiming to be 6'1". I don't wear hats, thus cannot relate to hat size. I however wear a size 62 motorcycle helmet. This is determined by measuring perimeter of dome from just above (15mm) eyebrows. I am 61.8 cm. As delivered new, this beanie is very snug and barely covers down to mid ear. I soaked mine in cold water for 5 minutes then stretched and tugged over my head. Finally, let it air dry at room temp fitted over 1 gal paint can to 'block it', preventing shrinkage. This worked for me such that it doesn't pull down as low as i'd prefer but its no longer so tight to give me a headache.

How many % merino wool?
