A window apparatus that can either be retrofitted in an existing blind or have the dimensions to fit into a new blind to allow a hunter to hunt with either a firearm or a bow. The window apparatus is made up of a frame having at least two panels. One of the panels is substantially transparent to allow a hunter to look for game. The second panel has a slotted aperture that is made up of at least one elastomeric membrane. The slotted aperture allows a hunter to protrude a portion of a firearm through the membrane, creating a barrier to stop scent from egressing, heat from escaping in cold seasons, and precipitation and insects from coming into the hunting blind. The elastomeric membrane can conceal the firearm further by matching the color of the portion of the firearm.
