I don’t think he’s far off base.  I wear all kinds of turtlenecks, including the cotton interlock variety of the sort sold by Lands End.  This particular variety is not for dressing up, as a fine merino or cashmere worn with a flannel suit might be, but it serves a very useful purpose for me.  I like them well fitted, but not skin tight, and I wear them in cool to cold weather, most frequently with jeans or cords, a tweed or corduroy odd jacket, and chelsea, paddock, or western boots (jodhpurs would work as well).  It’s a good combination for travel; comfortable, presentable in most non-business situations, and, with hat, scarf, and gloves, adaptable for most fall and winter temperatures.  Never fold the neck over on this kind of turtleneck; just let it scrunch down a bit like the turtle's neck does when he draws back into his shell.
