FIG. 3 is a front elevation view of the hat;
FIG. 4 is a right side elevation view of the hat, the left side elevation view being a mirror image thereof;
FIG. 5 is a rear elevation view of the hat;
FIG. 6 is a bottom view of the hat; and,

The crosshatched pattern, although shown intermittently, is understood to be distributed uniformly over the surfaces of the claimed design and is meant to represent material.
