Apparently the number of Cirri has reached a critical value — one of the manufacturers of pilot apparel now has an http://www.aviation-giftshop.com/cartdropcap/cirrus.htmlSR20 baseball cap for sale. Kinda neat.
Nothing yet for the SR22. Presumably the SR22 drivers all have either (a) thick masses of rich, lustrous hair, obviating the need for head protection or (b) no need for sun visors, since they have the craggy, squinting look of the multi-thousand-hour pilot. Or something.
Cheers,
