If you pull the size adjustment strap to tighten the fit, the two sides of the brim twist up or down in opposite directions.  This is partly because the brim is too stiff.  Also, attaching the side brims to the push-buttons on the side of the top twists the brim in opposite directions.  This too is because the brim is too stiff.  It's not a bad hat if you don't need to tighten the fit or attache the side brims.  I discarded mine.
