Hat providing ultra violet radiation protection

A cloth hat for warm weather use comprising:

• a main section capable of covering the top of a user's head and having a top with a side wall extending down from the top to a peripheral edge;
• a visor section connected to said peripheral edge at a front side of said main section, said visor section during use of the hat extending generally forwardly from the main section and having a width approximating the width of the hat;
• and
• a flap section connected to said peripheral edge at a rear side of said main section, said flap section during use of the hat extending generally downwardly from the sidewall of the main section a substantial distance which is sufficient to protect a user's neck from sun rays,
• wherein at least said main section and said flap section comprise first and second outer layers of tightly woven, thin, flexible cloth material and at least one thin inner layer of flexible cloth material sandwiched between said outer layers, said layers being secured together by stitching, both said visor section and said three layers of material in combination being sufficiently dense and opaque to prevent all ultraviolet sun rays from passing through the visor section and the layers to a user's head or neck and wherein said at least one inner layer comprises chopped strand mat made of polyester.
