The most common type of cascade type thrust reverser system in use today for an aircraft fan gas turbine jet engine employs a forward fixed cowl portion and a translating sleeve which carries a plurality of circumferentially arranged blocker doors on its inner skin surface.
It's a fine line between a cowl neck that is way too loose and goes down to your stomach and one that is way too tight and might as well just be a t-shirt. The best type of cowl neck garments are those that open just to the top of your decollete. Some people tend to see cowl necks as a way to put all the goods on display, if you know what I mean, but that's really just not the most flattering look -- it just looks like your shirt is too big.
