This hat does provide serious coverage and protection from the sun.  However, the brim isn't very stiff and the one I received was bent / lopsided.  Maybe it would have balanced out once it was out of the packaging for a while, but I can't say for sure.  The bigger issue is that I felt like I belonged on Little House on the Prairie while wearing this bonnet.  It might be very effective, but it is not stylish at all.
