        Abstract
A waterproof relief outlet in a chest wader consisting of a zipper having a zipper portion capable of movement from a closed position to an open position, wherein the zipper prevents water from entering the interior of the chest wader when the zipper portion is in said closed position. The wearer of the chest wader thereby has a way for relieving himself without having to substantially remove the waders and/or any undergarments. Further, this is accomplished in a highly simplified manner, wherein the wearer need only to grab a tab coupled to a slide fastener of the zipper portion in order to move the zipper portion from the closed position to the open position.             
         
        
            
                    Description
  
    
      
        TECHNICAL FIELD
      
    
    
      
        The present invention relates generally to waders and more particularly to a wader having a waterproof relief outlet formed therein.
      
    
    
      
        BACKGROUND
      
    
    
      
        Waders are sportswear that are used by individuals to protect against water penetration while fishing, duck hunting, or otherwise working in a stream or lake. Waders are rubbers boots that are stepped into and pulled up to the chest of the person. Typically, waders are held up by suspenders or some other type of device to maintain the top of the wader above the level of the water.
      
    
    
      
        One problem with currently available waders is that they typically do not provide an easily accessible relief outlet. Therefore, a person wearing waders must remove the waders, or at least lower the waders below their waist, in order to relieve himself.
      
    
    
      
        One proposed solution to the relief outlet problem was presented in U.S. Pat. No. 4,274,159 to Schmidt, in which a waterproof relief outlet having a folded funnel within the chest wader is disclosed. In this patent, a wearer of the chest wader can relieve himself by unlocking the interlocking tongue and then extending a funnel or sleeve through the interlocking tongue. The funnel itself is sealed to the inner surface of the chest wader. When stored, the funnel must be folded in order to ensure it fitting within its allotted space. However, this invention is complicated to use, requiring many steps for an individual to do before being able to relieve his pressure. This problem is exacerbated when a wearer's hands are gloved or not easily manipulated do to cold temperatures. Further, the interlocking tongue is not waterproof; it requires a cover to ensure that water does not leak into the interior of the wader when the funnel housing is held in a closed position.
      
    
    
      
        Accordingly, there is a long felt need to provide an improved wader having a simplified waterproof relief outlet that prevents ingress of water into the waders not heretofore attainable.
      
    
    
      
        It is therefore an object of the present invention to provide a wader having an easily accessible waterproof relief outlet.
      
    
    
      
        SUMMARY OF THE INVENTION
      
    
    
      
        In accordance with the above and the other objects of the present invention, a simplified waterproof relief outlet in a chest wader is provided. The wader has a zipper secured to a center seam therein. The zipper, in its closed position, is completely waterproof and is enclosed at both ends without any additional steps. A wearer of the chest wader can relieve pressure by simply unzipping the wader.
      
    
    
      
        Other objects and advantages of the present invention will become apparent upon considering the following detailed description and appended claims, and upon reference to the accompanying drawings.
