Monitor hoods, they really work

I came across this late 90’s picture of my first ECS set up on Ralph, the boat’s that’s still looking for a new owner, yee scurvy dogs (hey, yesterday was supposedly Talk Like a Pirate Day). That cloth-over-something-stiff hood velcroed to the laptop made a tremendous difference in usability, even on cloudy days. I got it from Hoodman but now they only seem to have a hard plastic ‘desktop’ model (do not get the pop-up version, as you have to put your head too close for boating). Captn Jack’s has one that looks pretty good, and there’s also GlareStomper, which specializes in fabric and stiff foam hoods fitted for smaller machines like Garmin 492. Anyone know of other choices, besides some cardboard and duct tape?
