     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide a hat which has an extensible visor to be extended. 
     Accordingly, a hat comprises a main body, a fixed peak disposed on a front portion of the main body, and an extensible visor engaged with the fixed peak. At least an insertion block is disposed on the extensible visor. The insertion block has two opposite sets of lateral teeth. At least a pair of L-shaped racks are disposed on the fixed peak. Each L-shaped rack has a front block and a plurality of serrations. Each sets of lateral teeth engage with a respective one of the plurality of serrations. 
     In accordance with a first preferred embodiment of the present invention, a hat comprises a main body, a fixed peak disposed on a front portion of the main body, and an extensible visor engaged with the fixed peak. An insertion block is disposed on the extensible visor. The insertion block has two opposite sets of lateral teeth. A pair of L-shaped racks are disposed on the fixed peak. Each L-shaped rack has a front block and a plurality of serrations. Each set of lateral teeth engage with the respective serrations. 
     In accordance with a second preferred embodiment of the present invention, a hat comprises a main body, a fixed peak disposed on a front portion of the main body, and an extensible visor engaged with the fixed peak. Two insertion blocks are disposed on the extensible visor. Each insertion block has two opposite set of lateral teeth. Two pairs of L-shaped racks are disposed on the fixed peak.
