Unfortunately, the open carry law for a medieval flail is a bit ambiguous, so might as well play it safe with a soft beanie. (or tuque, for those of you!)
These soft knit beanies are high quality, soft, with a tight stretch, so they are one size fits all but won't lose their grip quickly like many knit hats.
Both beanies have a cream-colored stitched patch with an illustration of a medieval flail, vaguely heart-shaped, as we are romantics around here.
Note: The black beanie has a bit more height than the pink, although the difference is minimal :)
