Hat is worked in thicker ribbing with yarn held double, then in the much higher gauge stockinette/reverse, with yarn worked single in the body. Judicious increasing at the rib to stockinette junction provides shaping to give a defined slouch to the back of the hat. Longer interval decreases with alternate stockinette continue this look for a decidedly slouchy topped rasta/reggae-hat. You can opt to change colors in the ribbing and/or in the alternate stockinette/reverse stockinette.
